That totally depends on the project. Some people want realistic portraits of their cars, and some just want a simple sketch for a tattoo. It really depends on time. Some stuff I'll do for free, like a five minute sketch, if I got the time, and other stuff I charge for. It really does depend on the scope of the project. Do I need to do research, is it from a photo, or do I have to make the whole thing up. I also do trades sometimes, if it's something I want. Either way, I usually find a way to get everybody what they want. What do you got in mind Mike?
