A practice I don't do all the time, but I had a gentleman call me about getting a caricature drawn at my home...I usually say no, send a photo, but he wanted it right away, he had been at an event I was drawing at and didn't get a chance to get one drawn and was from another country and wanted one done. So I pulled out the Prismacolor Artstix and threw some color on, it started me thinking that if someone just wanted "head and shoulders," I preferred drawing the caricature with the client sitting in front of me rather than looking at a photo. The client went away happy.
