yeah you should change the color of the hair, type of cloths, the characters gender, and if you can, the size of the zip... yep, thats pretty much what you need for me to be pleased!
COME ON PPL!!!
it's HIS work, his choices, his style. and we gotta look at it for its worth, not for what we'de like it to be. hell, then I'd ask him to make a girl and show the boobs!
it's nice you sugest more contrast and all, because you could see the details better. but not cause "it looks better". it's up to de artist to define what looks better in a piece of art. it's his message, not ours.
in game art, ok, id say "i dont see what weapon he is carring, make it bigger" or "I cant tell de diference bettewn the hero and the vilan". thats all good critics. and "the head is too big" is good to... if he was going for realism. which I know is not the case.
its a work of art. eighter you like it or not. you dont go and change it till you like it. its not a lamp, or a couch, that you pick out of a catalog

I think splatpixel made color choices because he feels thoes are the best. and the size of the head is his choice too. why change it? so it can be the booring same old proportions-correct kind of human drawing? hes past that I'm sure!
give the man some room to express him self!
