People ask me to draw their dicks, draw their asses or to draw them for free. I used to have girls show me their boobs for a caricature. I've even had people fight while I was drawing them. Sometimes people think my sign says cigarettes instead of caricatures and they ask me what kinds I have. You have to have a lot of patience to do this.
Guys are more fun to draw.
You can be more blunt. If they have big ears, you can draw big ears and they don't get mad. They're not as sensitive as women. A couple asked me to draw what their kids would look like. They liked it except for the Mohawk and piercings.
