How weird - I swear I commented a long comment on this last night! Argh to computer glitches! Anyway, this is a lovely illustration. I'm not familiar with the story of the black swan, so I can't really comment on the context of the illustration's back story, but I'm guessing maybe it's the same as the black sheep? But I agree with Chip that a cool colored background would really help make the swan pop more. Also, I'd maybe add some greys to the swan with a white highlight or two on his feathers and feet. That will all help to make him look a bit more dimensional. I love the pose!
