okay, before a mod comes in and says it, I will. Sonic, calm down, though that was harsh. Don't be so mean at him, he's new. And Nitro, try to use constructive critism, not it sux, and put more time into it, fix the face, give him examples on the model that he can work on, besides, he didn't say it was his finished copy, or that he was an expert at it, give him a break. Didn't mean to sound mean if it came out that way. Okay, back to the discussion. Anyways, these are the things that everybody said in a list:
show goku's abs and muscle on his front side
add little red lines undr his eyes
make the tail go down instead of strait out
the head hair (lol) has too few spikes, it has a few spikes that go down to his shoulders, so add some more hair
the skin tone needs fixing, when did goku get a tan? j/k, just lighten the skin tone
other than that, I see no problems, other than the hair on his upper torso looks like a shirt, but hey, you can't really avoid that.
