You're on a roll ! Very cool. At this point I'm sure you could do both straight portraits as well as tight caricatures. I think the caricature adds a heck of a lot of interest and it's something that would have greater appeal. I mean people can take photos and get pretty good shots of the actual person. But a caricature adds a lot of freshness and often lightens and flatters.
Good stuff.
