You seemed destined for the toy/statue market.
Not familiar with characters, but understand the concept. I like your attention to detail. The waxes look pretty clean too. Your style is a nice mix of realism and characterization. By way of critique...There might be an issue with the proportion of the biceps to the forearms (it could be that the triceps are a little underrepresented) on Captain Hammer...and personally I would flare the right-hand pants pocket out so the hips look more symmetrical.
Is this where you are wanting to go with your work?...the commercial market? There is certainly a lot of work there. Geographically you're well situated on the West coast.
