Here is the reference photo (found on pinterest, of course). I had to squish the drawing to get them all in:
And here is the progression:
The birds are darker than the reference photo; I should go back and lighten them. That will probably make my darks stand out more. I think my printer is partly to blame, once again, because the picture I used to paint from was darker than the one above. I'm noticing that I tend to paint things darker than they actually are, though-- something to work on.
So, I did go back and lift some of the color off of the birds. I can't decide whether it helped or hurt. I kind of liked them darker. Oh well!:
