As for content,
- i dont agree with zhonyas. You will be weighted to the AD side of things, and its active wont allow you to be a tank at all. I would grab a Sunfire Aegis. i consider this a must have for any tank.
-when you take out zhonyas you will have no more AP and you should switch Sheen in for a Trinity Force. Same passive, but with HP MP AD some Movement speed and its passives are awesome with its slows and 150% AD adding onto your next basic attack
- Thornmail is a situational item only used when they have a heavy AD hitter on their side like Tryndamere and you can get the full use of its passive. If you dont have that hard hitter i say go for Randuin's Omen. Health, Armor, great slowing passive, and its active helps a LOT in chasing to Pulverize then Headbutt back into your team.

Its an alright build. I still feel there are some holes with the view and with the content.
no vote

Dont make it all in one section, actualy use the section system already there for you, also, use a lot more pictures and anything so that in the paragraphs you have Lich Bane instead of
