I love those projects that I can really get into. This one didn't start that way, but it helped when things went right. A friend who I've worked with before requested I do a motorcycle illustration for something he was working on and I jumped at the chance to work on something unique. He said not "cartoony" and not too detailed, but something he could later dismantle and change the color if he wanted to. This took a few hours, but like I said, it helps if you enjoy what you are working on and things seem to be "going well" (like shapes seeming to fit together well, colors and shading turn out good, etc.) as you're working. Haven't received word back from him yet, but I'm hoping it's something he can use. We'll see.
