I see what you were going for with the chest, but it just doesn't work.
The piston add-ons are a little flat (they should probably be extending past the shoulder armor to have the proper depth), and the actual chest plate piece is situated so low that it doesn't look right (his pecs are in the middle of his torso).
My only other complaint is his thigh armor. Again, they're a little flat.
Also, Ice wArrior, correct?
The underlying build is solid though, nice work!
