Holy crap this is gorgeous. The lighting is amazing and the way it lights of the feathers and lights up the sky is absolutely breath taking. I love all the detail you've put into the feathers and clouds, it really makes this piece.
The feathers are cool! I remember having to do an art project that combined 3 animals, and so I chose a human, wolf and bird. I did feathers in with the fur, but not anything as good as this. The background is awesome as well.
