Well, if you look at Hallmark cards and illustrations in children's books, I would think there would be a market for illustrations of cute children. I understand what Pakled says about a live-in granddaughter being cute enough for him - I had and still do not have any interest in the teenagers because I had two at home and now that they're are in their '20's they still act like teens. I had no desire to render teenagers, LOL!  Has anyone ever sold any Poser illustrations for books? I would think children's books would be a good market to try to break into to.
PS What happened in Portugal????
