thanks for the help i will really look in to all of this

A description of what you are aiming for would be nice.
Skills:
I would put a point in each skill for your first 3 levels, that way you have everything at your disposal. Also, at 16 I would put another point into your ulti.
Items:
Typically when I build a tank, i prefer to get hp and hp regen first, so, I would suggest warmog's after boots. Also the boots I would change depending on your enemies, either ninja or mercs. Also, with your item build, you are leaving yourself exposed to casters who will gladly rip you apart.
Masteries:
I have noticed that minion damage seems to add up when I target champs, so I would prefer taking 2 points out of Ardor and putting it into defensive mastery, it helps early game. Lastly, I would take 2 points out of perseverance and stick them into good hands. I know you shouldn't be dying much, but as a tank you never know how things are going to go down. If you use teleport or ghost walk, I would instead put those points into which ever one you use (or both if you use both). The reason I dislike perseverance is, 6% hp regen really is not much. if i have 200 hp/5, im getting a whole 12 more hp every 5 secs.
Runes:
Only thing I highly suggest is keeping the cd reduction glyphs, but getting dodge seals. For the other runes I am flexible. Perhaps MR marks or magic pen (ki strike and vorpal blade). As for quints, I have never tried the xp bonus runes because im too poor for them, but MR, dodge, and magic pen probably would not be bad either.
*I only suggest magic pen if you plan on killing some people or doing damage while tanking, it should not be your focus, tanking should.

Other than that, great start and try to follow through.
