Here is Stocky Businessman With An Emo Haircut, original character do not steal.
Honestly, this started out as just an attempt at making a design with a stocky bodytype. It went to a weird place. I don’t think the attempt was terribly succesful. I tried getting his belly across with shading, but it didn’t quite work. It would have been easier if he was facing directly forward.
I think it worked out pretty well- I can definitely see what you tried to do with the belly. Maybe you could do some masking with the jacket to make it look like it’s following the shape of his body? And maybe some shading under the bottom of the jacket would make it look less like it’s sitting flat against his body?
