Well I figured I'd scan in my progress and discovered that the scanner is putting weird lines across the artwork. I'd guess it's dust on the mirror, but it's bizarre that it's only happening to the color images.... and it travels diagonally? The hell. I think I can open it up and try to clean it, but I'm sort of afraid I'll break it forever.
I didn't bother to correct it since it's and in-progress image, but I guess I can plan on having to fix the finished piece.
Then the sun went down and I couldn't paint (gasp) so I remembered that this still needs to be finished (TECHNICOLOR DARGON)
And this is close to three hours, a lot of it having to go back and play Captain Color Correction. She's getting close to done tho.
