Art de Combat in my sights

I just signed on to compete at the ART de COMBAT at the Enchante Gallery in West Branch, Michigan on Saturday, May 30 from 4-7.
Here's the premise: artists come in, set up and at 4pm they begin creating a piece of artwork for the next three hours. During this time, the "audience" wanders around, watching the artists, ask questions and vote for their favorite piece. Also during this time, drinks and food are provided (beer, hors' d ouvres, wine, etc) for viewers and artists. At 7 pm the artists stop and the ballots are counted. There is also an auction for the artwork that's been created at the event. There's a 1st, 2nd and 3rd place winner. Part of the auction proceeds of the evening goes to charity, I do believe, and the other part to the artists whose pieces are bought. This is the second art battle at Enchante, but the first I've ever participated in.
Now, here's where it gets interesting, at least for me. I don't know what I'm going to do! So, I'm asking people to give me suggestions (remember that I am, for the most part, a portrait artist). So if someone suggests Jack Nicholson, and you like that idea, let me know and the idea with the most 'votes' has a better chance of getting done. OR I can do a drawing or painting of a live model. If you come to the event, and want to be my model, let me know. Then you or someone you bring with you can bid on the artwork. Or if you want a portrait of someone, bring them to the Art de Combat and they can sit for me for 3 hours (breaks are acceptable, of course). You can e-mail me at jasonnuttall@yahoo.com to give me your suggestions, or mention it on my Facebook or my MySpace. I will post a link to Enchante once my internet connection works right.
