The information in your guide is very useful, and the build is effective. However, your BBCoding is lacking. You seem to only know the [ icon= ] code. A great code that you should know is:

[ [Name of Champion, Skill, Item] ] *Use without spaces between brackets, gets you Nautilus

It's great for breaking up the giant walls of text that plague your guide at the moment.

The last thing I'd change is switch the Greater Mark of Healths to Greater Mark of Magic Penetration. The flat health reds aren't that great, and the magic penetration greatly increases your damage, plus they're useful all game rather than just level 1.
