I got put on to this postcard by Shag over at Firestorm Fan, and it certainly is a nice image. I wish I could find a bigger copy, but you make do with what you have sometimes.
Anyway, I really like the symmetry which Perez uses here. Besides their arms and wings, notice how the strip on the right boots line up, and then is nicely broken up on the left. I also dig Shayera wielding the big two handed axe!
