Nice. I started a response to that, and finished the sketching. But I tried scanning it in, then just playing with levels to get the line art, which seemed a lot faster. But it looks like it's going to require at least as much work to clean up the lines now, as it would have to just retrace them in GIMP like I did for my other pictures in this thread. Anyway, you can expect an attack from me within the next few days.
