This is a mock-up of the next piece I'm working on.
I spent a few hours this morning making sketches and then scanned them into the Gimp, then I layered the crowds and birds over the image. The crowd images are all from the Jimmy Buffett Oil Spill Concert. The birds are ruby-throated hummingbirds. I sketched out a few other feeders, but I like the feminine aspects of this one--she's all curves.
