The two lines are simply a carry-over from the original image I used for the raven. And the highlights for the wing are there. They just happen to not be in the exact same position because the raven is not the same and lighting is not same either.
I can get rid of the white lines easily enough, but remember that my aim is not to create a duplicate of the original, but to make high quality versions recognizeable as the original design. I probably could just draw new versions on paper, then ink them, scan and colour them. But using available source images is much faster and produces acceptable results so...
