i like the last post that you have done.
just some sugestions.
the fingers look funny (but you know that, and they are hard to do)
the skin is a bit light
perhaps tan lines
also to make the skin look a tiny bit more realistic lower the reflectivity and the spec.
also raise the emit a tiny bit (eg 100 or less) so that it looks like a more natural skin colour as shadows arn’t usualy that strong on skin.
also the blue singlet shoulder strap looks like it goes around the back of the neck and connects to the other shoulder.
i think it may work better not going around the back of the neck so high up.
more wrinkles in the pants would also be nice.
perhaps use a texture and the noise function (don’t know if that would work just a sugestion)
the forearms need work.
the face is perfect i think.
nipples sticking out through the singlet wouldn’t look out of place!!
actualy they would make it a bit more realistic and funny.
hairy chest texures and belly textures would look great.
belly is a bit out of proportion with the chest
i think it would look a bit better being smaller
the edges of the singlet look a bit curvy this may be fixed with stiching texture around the edge or sharpening the edge a bit.
if i have repeated anything else someone has said i’m sorry.
i know its early days so i listed everything i could to make it easier for you. i’m not trying to be harsh. just to help.
it’ll look good for the end of the year!!
