Gyrfalcon

Yippee!After 4 years,I have finally worked out how to draw birds of prey!This is a gyrfalcon(It's a non mythical bird of prey from Earth),an extremely powerful and agile flyer.I first saw it's piccy in my Giant book of animals and I wondered if I could draw it and this is the result.But I think I made it's left wing smaller than the right one and it's left leg is in a weird pose,like it's broken or he's about to fall over.
