IF: Bicycle

I did this really quick little sketch for Illustration Friday. The theme this week is bicycle:

I'm trying to get myself in the habit of doing quick warm-up sketches in the morning where I have to produce something in a relatively short amount of time. It can be anything at all and it doesn't have to be good. I just have to agree with myself to leave it alone after my allotted time is up no matter how badly I may want to fix. Like those tires, for example. I rather dislike the tires, but I'm forbidding myself to do anything about it (which is hard when you're me). Anyway, I'm hoping this kind of exercise will gradually help me to loosen up a bit as well as provide an opportunity to play with media I seldom touch. Today I used micron pens and colored pencil. I can't remember the last time I used micron pens...
