All things considered, it's a very good set of sprites. The flapping animation would need to be a bit more realistic, though (three, four frames or so to flap). And the collar is missing, too.
But other than that, it's a really good TMC-styled set of sprites. So it doesn't match the SwS bird at all -- so what? Link is an adult in SwS. So Leduardo is doing a good job on that sprite. I'd love to see the end of it! (Of course, we'll have to wait until SwS is released, first...)
