r1k, look I has updated contrast

the skin has very low contrast while the clothes have high contrast.  At 1x you cant really tell that the skin has any shading at all, so perhaps you should darken the skins shadows some.

Dpixel, thank you too, I think should change the palette, do you think?

This isn't bad at all.  I agree with tanuki also.

Tanuki, thank you, but I think that the shadows did not work

You're getting better at these.
