I'm not sure.
It's slow work, but digital painting is fun. I've wanted to do it for a long time, and tonight I drew a dragon head using help from Jessica Pfeffer's DragonArt book. I scanned, I started to ink, saved that and switched to painting.
The above represents 1.5 hours' work. Like I said, slow going.
Ah, but! It doesn't totally suck! And that, dear friends, is Progress.
