For TWENTY bucks (the demand was so high I had to increase my price) I'll do a little sketch for you--not a super duper crazy-detailed thing, but a fun sketch that I'm pretty sure you'll dig. I call them "fourths" because of the size: they're 4.25" x 5.5", one fourth of a sheet of cream-colored cardstock. You can see some past examples here on my Flickr, or ones I've done since setting this offer up here.
You're welcome to stick in a word or two to give me direction, like "scared cat" or something--but these are cheap sketches, I can't be looking up photo reference or interpreting pop songs or stuff that takes real thought. SO I reserve the right to reject any direction. I probably won't, but just so you know!
