I have very little experience with character modeling, so I decided to give it a go:
It’s still pretty rough, but it’s a start. When I’m done, I’ll do a retopo and get him down to a game ready poly count. where I can take all this detail and bake it in.
Note that the proportions are meant to have a slight cartoonish feel to them, but should be largely believable. If there are any suggestions in any field, please let me know.
