-1 for the Beserkers Greaves

This is your very first guide but that doesn't change the lack of knowledge you have. I will tell you things I find wrong in your guide:
I'll start with solo top:
1. You remained in season two. I mean people start either Long Sword and two health pots which I don't actually use but it seems to be good actually. The second one and the one I use the most is crystaline flusk + 1 sight ward and potions. This is giving you that early ward and some nice sustain letting you stay in lane for a long time and not getting ganked at all, still this is my preference.
2. I would rather evolve the Void Spike or Leap over Taste Their Fear since it is more usefull later on. Why? Well, with evolved Void Spike you can deal more damage then when you evolve your Q and you can clear camps faster.
Leap has a really big range when it is evolved thus making it easier for you to escape sticky situations.
3. I find your item build really wrong. First of all, Berserker's Greaves aren't viable on such champions. If you are an assassin without tenacity, it is most likely that you will die if the enemy has a smart support. And you don't need attack speed, you need pure AD. Maw of Malmortius isn't good either, you won't always face an AP carry. Warmog's Armor makes you lose a lot of burst damage so does Trinity Force. You will say that Sheen passive thing but I will do the maths. And now you think that building glasscannon is risky but that is the most viable way of playing assassins, else you will remain stuck in the middle of the enemy team not being able to kill the enemy carries. And you don't take a The Brutalizer, nor a Black Cleaver, man this is wrong.
Jungle:
1.I am sure you die if you start with Taste Their Fear, Void Spike is much more usefull for it's AoE and for the heal you get since you will be in the melee range. And you say start blue, wroooong!
You must go wolves->blue->wraiths->wolves->red->gank or again clear camps or you if you save smite, you can go to red directly after blue and thus giving you easier time ganking.
2. I find it really wrong to evolve your Taste Their Fear when you can evolve Leap cause your ganking potential increases with such a long range gap-closer.
3. Again, wrong item build.

General:
You say you are squishy when you build a lot of health and MR, how come?
You lack damage early game... Have you ever played Kha'Zix?
With your build, you won't know what means a great burst.

Just look at what I said, and you will understand what a wrong guide you have.

great guide bud. I just got this champ a couple days to go and this guide is a gold mine of info for him.
