Zombie Close to being good
Well the colouring is done top-notch, i must mention that before anything.
It does look like its missing some sort of structure to the body, its very off. Even cartoony characters have equal arms and legs. Then to the head, nice colouring again. But try to keep an eye on the details: like the brain and the shape of the head; It looks like he is tilting his head, but his eyes didnt move.
Nice work, keep improving
