During College, we had an assignment to model 3 things. One of them I was proud about was this High Poly Pokeball. The assignment consisted of 3 models, one of them being something we do high poly.
I at first, thought modeling a Pokeball would be easy as pie, turns out not quiet. There is some unwrapping woes, expesially about how to model the interior. The references I used helped a lot at the very least.
