After looking through the extensive (and awesome) miniatures on the HF site, I seem to have noticed that there's a lack of adventurers (or otherwise human miniatures) that are male adolescents with or without long hair (except the minstrel). Also, there's a similiar lack of male miniatures that are lanky with or without being awkward (except Wolsey) or very thin in general.
Not that being very thin is heroic, but many of the adventurers seem to be of the non-stereotypical hero stock. I'm not sure how much interest there'd be in this, but I thought I'd just point it out.
