The original was 600x600 pixels because I like to work large. It also looked horrible at full size; I didn't bother cleaning it up since it was only going to be shrunk down anyway.
Today, I pulled out the original and spent some time retouching it and trying to make it look furrier.
[EDIT: This is, of course, another digital piece. This one's actually all digital -- no pencil sketch involved. Sketching on the computer seems to take a lot longer than it does on paper. It always makes me wish I had a larger monitor. And I already have a 19" monitor.]
