Chances are if you ever see me using a computer, I'll surely have two things open. My Gmail and CHUD.com. CHUD (Cinematic Happenings Under Development) is my favorite movie news site. It's not really for the news because that stuff is everywhere. It's the writers and their commentary for each bit of news that keep me coming back there.
Over a year ago, I finally started posting regularly on their message boards. Since it's a movie news site, you'd think that people would mostly discuss... movies? This isn't actually the case. Its membership loves to talk about lots and lots of whatever. The community is also close-knit enough that they have lots of inside jokes and also post images of themselves in a thread called Chewervision 2D.
It's from this thread, I started doing caricatures of several members. I did them to pass the time for fun and posted them in the thread. Unexpectedly, it took off. People really liked seeing themselves represented by my doodles. So I also began taking requests. They are of varying quality. But I'd like to think that I've improved steadily by just drawing constantly. This is the most recent one I posted.
I can't say that I have a definitive style. Sometimes, I do a fairly realistic rendering of a person. And then I'll do a much more cartoony version on a whim. I don't think I've found the ideal balance yet, but it's been fun trying to look for it.
