Thanks, guys.
Ribby, I don't have any other computer-based work, but I'm thinking of doing some traditional LC sketches at some point. I'll put them up when I've done some, if anyone's interested
blkrbt, thanks
LuciousLisa, I didn't trace, I just used a screenshot for reference and copied the shapes using the skinny Paint brush, then went over it using roughly similar colours and the other weights of brushes.
