I know how you feel I'm not so great with proportions but i hope this helps. I think his hands are a bit big and also his head. Two heads should fit in his torso here it looks as if only one and a half can and also I think his tail should be a bit longer. anyways I hope that helped you out
Well.. since he is Sora from KDH.. his head and hands are supposed to be really big XD; And I already knew about the tail thing.. everyone's pointed that out so far. But anyways thanks! ^^;
