at first look,it looks really good cuz the bleached bone is well done,but...
get rid of that HUGE mold line.that takes it down so much.the sigils shouldnt be the same color as the armour and some parts could use some extra highlights.some parts look a bit sloppy,like the right knee and the area around the eyes.i also would remove the lettering on the fist.maybe too many colors.looks allright but all in all it could be much better.sorry that wasnt too harsh ^_^
