First is a hand-drawn picture I got from a request over on NaNoWriMo:

Those are the two main characters. Cameron is the POV character, and Michael is his boyfriend 3nodding
Next is one I made myself, using that aforementioned clip-art set!

That's Michael's twin-sister Miranda (put together and colored in Photoshop CS4). I'm not sure if I want to make more characters from the set, though, because one: it's close to NaNo, and two: the set is kind of limited so not all of my characters would work. I guess we'll see!
