overdithering and a boring palette detract from the piece, but it has plenty of potential. try tinting your greys so they aren't completely desaturated, makes them more interesting. straight browns are kinda dull, some hue shifting coul fix that.
Good. I especially dig that hi-tech device in brainy guy. But something doesn't let it to be truly great, and I am not shure what - maybe palette, maybe unrefined lines here and there, maybe something that I don't even notice. Good, as I said, but there is still a way for improvement.
I have some reservations about the horizontal shoulders, but they are otherwise pretty good.
Thx guys for your comments and advise really appreciate it.
I must say i didn't understand everything that was said, will try to figure it out and maybe ask around in the forums.
