Two days ago I drew at a junior prom. I believe that there were over 200 kids there, and only one caricature artist. I had a great time, but I had to keep the drawings really simple and really fast in order to get at least a third of the crowd drawn. I had the most fun drawing the faculty when there was a little down time. I tried out doing some of the gray tones with a warm gray prisamcolor marker 30% and 60%.
It went really great. Next year they wanted to hire me again. Although, I would bring two of friends along to help. I'm drawing at a wedding reception tonight.
Will probably use the gray markers again for coloring. Hopefully some funny pictures will insue.
