The Financial Advisor
I get about a three line description of the woman for these assignments. "A young female financial advisor, arrives at a guy's house to help him with taxes, etc. She is beautiful, but a bit tired looking, still sexy, etc., She leaves the apartment, and the guy can't stop thinking about her". I then have to visualize the character, it's been fun.
The people I've been working with are great, the time zone and language differences always make for funny e-mail banter.
Here are the two previous illustrations:
