Im sorry to be rude But it doesnt look like goku.. Not at all.. The hair is so wierd and waked out, it has like 4 spikes. And hes so puney. You made him so small. The skin, even for cell shaded is terrible, the face looks nothing like goku and the wrinkles have no detail and are shaded pretty bad. The chest doesnt even have any muscles, nor the arms.
I dont know, dont like it, look at some refs.
