Glitch needs some help with not sucking.

The dark dark red hole is used for reference, that's where his arm goes. I looked at some more reference pictures and the less dark red lines are the seperation of cloths that are on most other jedi robes. Im bad at explaining. But it should make sense later. Then next to it is without those lines to show shape better.
Is his upper body too small? Thats my main concern right now because I cant tell. :/
Would someone please tell me if the size is okay? And any other criticism is welcomed.
