had to see it in-game since your screenshots suck

since you're going for a "realistic" painted look, the cartoon bored face is going to be too out of place
also, ears
and for the body, well... Saitama's costume is really simple and there's really nothing interesting you can do with it..
add more wrinkles and don't map the knee on the shin.. just leave the knee at the knee joint
i know this is a very early wip, but only body textures is definitely going to make for a boring set.. since it's a boring costume

first off let me say, being an asshole to people who provide valid cnc is one of the last things you want to do, especially if you want cnc.

second, the style of the head doesn't match the set, as stated by TPK.
Either go full Cartoon, or full realistic, the shadows are really badly made, reminds me of some of my early stuff.

this might help

don't ever use jet black to shade. (this is my opinion, you may be able to pull it off when you get better)
