[edit again]
after talking to boing and panda and some constructive crits after, I'm up to version 4 and i'm thinking tis the last D: haha xD and since i was already working my butt off i decided to draw in his hair too :'D
------------------------------------------------
Fixed some parts: nose/lips/shadows
------------------------------------------------
Added a paper texture to make it look like it was traditionally done aharhar >.> in truth i don't think i can do stuff traditionally now o_o besides my scanner's busted =\
I don't think I captured his face exactly but this is a lot better than my first try at realism...with him as the model too *coughsfangirlcoughs* His nose is really hard to draw and the lips were hard to shape ; 3; but i'm still quite pleased <333 Practice sure has some effect :'D
