Your cheatsheet doesn't look bad per se but it could definitely see some love. Especially your item section appears to kinda lack content. I understand that you explained all of that (and much more) in your guide later on and simplifying it into a cheatsheet might seem like a waste of time. But sometimes your reader will be a clueless auto-filled first-time Zed player who has 1 minute to figure out what to build before minions spawn. People like this don't have time to read your detailed guide chapters and need the info ASAP. A clean, organized, content-packed, informative yet still compact-sized cheatsheet can go a long way :D

★ For your rune section, I like the way you named your blocks, it's clear and simple as it should be. Though I believe you could still write some extra info into the notes. Ideally nothing too long, just some very short explanation or overall strategy with these particular runes. How is Conqueror gameplay different from Electrocute? Or is it the same? Is there any situational rune edit available?

★ Both your matchup and synergy sections feel really empty. From my experience, detailed matchup section in the cheatsheet is one of the most reader-requested features. Don't be afraid of this section, from your videos I can tell you absolutely have the knowledge to fill it with <3

★ Your item part of the cheatsheet is where things get a little bit undercooked however :d There are so many things you can possibly do about it to make it much better.

★ My first advice would be to simply add more stuff to it. There are so many things that can be added. What starting items should the reader buy? What should they buy after their first recall? What item should they rush first? What are all the mythics available? What are all the boots one can consider? You can mention extra-ish items like Elixir of Wrath, Control Wards, or a Refillable Potion. Take inspiration from how much content other writers put into their cheatsheet.

★ Next step would be to organise it all. Dissect different parts of your cheatsheet to make it a bit more comprehensible. In your guide, you are putting all the possible items under one banner. But consider just how much cleaner it could look if you split that section into multiple smaller parts. And don't be afraid to use Item groups, it's an awesome tool that can increase your organization level even further up!

★ Last but not least, again some more notes would really make your cheatsheet a bit more informative. When combined with the tip above, you can easily add some very short bits of information into respective item pools. Even something as simple as "Build X against mages | Build Y against other assassins" can go a long way.

★ I just noticed you also have some items ( Plated Steelcaps and Serpent's Fang) in your guide chapters but not in the cheat sheet. Sorry for being nitpicky :D

When it comes to the presentation I think despite some loose screws here and there, your guide is on a quite good level :D. Your graphics look awesome and your structure is mostly cohesive and understandable. I have very mixed feelings about these huge youtube links however. They are really massive and compared to the rest of the guide, they just look out of place. I understand the desire to show your work from other platforms, but I wonder if there is a visually more appealing way to go about it...

★I L.O.V.E your headings!! They are simple yet very cool and distinctive!

★ I also absolutely adore the custom font you have decided to use throughout your guide. It looks really awesome and stylish - great choice! <3

★ I like the strong sense of theme your guide radiates. The yellow really doesn't look half bad and it is giving your guide a sense of cohesive and unified design. 10/10!

★ If I were you I'd maybe consider recoloring your TOC. The blue looks kind of out of place - especially when there is such a strong potential in your yellow color coding. If you're afraid that the yellow won't look very good, perhaps consider different shades/brightness levels.

★ Your Inroduction chapter is flawless <3

★ For your rune section I am very confused why would you put something so important into spoilers. Runes are essential knowledge that deserves to shine and radiate into your reader's screen.

★ The spoiler issue aside I think it would be great if you tried to unify the size of the text on the side. For some runes you use 5 line-long explanation while for others it takes only 3, 2, or even 1 line. Is there really nothing else that can be mentioned about them? Anything? It will make the formatting look way cleaner if every rune-describtion will take on average the same amount of space.

★ Your "What to build" chapter is OK overall. Personally, I'd recommend using a bit different way to format a chapter like this as it would make it easier for the eyes - but that's just a minor detail. This chapter looks fine overall.

★ Your Item guide chapter, I noticed there is a slightly larger space gap between a few items than the rest of the chapter. Again, sorry for being nitpicky, but I can't help but point it out :D

★ Ability chapter is OK. Probably not the best format out there - but it's not the worst one either.

★ I'm afraid your matchup section is getting kind of slaughtered by these huge youtube links :d They take so much space and are looking very out of place. If I were you I'd get rid of them altogether, but you can still hide them in spoilers too. Keep in mind that you are already referencing them in your hyptertext-ed links. There is no need for another link in a form of a huge rectangular youtube thumbnail window :d

★ I love your early/mid/late game chapter design. Can't stop staring at the beautiful font side-headings <33

★ Your summoner spell chapter is... kind of basic but still doesn't look bad by any means. Though If you'd want to up your guide-making level, I'd look into at least slightly more advanced ways to go about this chapter - especially since it contains just 2 summoner spells.

★ Your fun time chapter seems to suffer from the same cause as your matchup section. Though I must admit that the end of the guide is probably the least disruptive place to put these youtube links in.

Content-wise I think your guide is doing alright. You cover most of the basic knowledge and general information. However, there is still a lot of room for expansion - especially when it comes to advanced mechanical micro topics and the matchup section. If you're happy with the size of your guide, then by all means leave it as it is - there aren't any major flaws when it comes to content here. But if you want to be the very best (and I know you can be based on your extensive Zed insight!), you'd have to tell us more! :D

★ Consider adding more chapters! You are an experienced Zed ex-challanger player. Who else could teach aspiring Zed newbies aspects like warding, wave-managment, roaming, flanking, positioning, combos, etc. :D Currently these topics are mentioned in your guide, but I believe they are all major enough to deserve their own in depth-chapters!

★ Don't be afraid of adding more information into your Items/Runes chapters. There is always something cool/interesting/important that can be added. And some of your entries-descriptions are quite brief - tell us more :D

The automatically generated table of contents seems to not work correctly. I know you already have an awesome TOC in your guide, but consider structuring your chapters in a way that would fix this issue, if possible :p

★ If I mentally skip the huge youtube links from your matchup section, the chapter quickly becomes... very empty :d There are like 40-50 possible encounters a Zed newbie can face in their ranked games. Consider giving them some tips on how to win the game against them. The Matchup section is without a doubt the most difficult chapter to write, purely because of the level of effort it takes. But If you'll check guides like [13.1] The Ultimate Guide to Akali the Rogue Assassin FR/EN or Ultimate guide to Urgot you will find just how INSANE this chapter becomes if the writer takes their time to maximize its potential. Of course, these 2 examples are from extremely experienced writers. There is no way a mere mortal can come anywhere close to their level, but I just wanted to let you know how much power matchup section can hold.
