Love the foot position, low angle and the drop on the beak. Nice crop. If anything, the change from gray to blue in the bg is a bit distracting but not a big problem because it is soooo oof. This is really nice.
An excellent photo, as noted above. I agree with Krijn that it would be even stronger with more room on the top and right. I don't mind the blue at the top, but the white in the upper left tends to draw my eye. You might consider toning that down.
Great details, angle, droplet on the bill and light. I would put the bird a bit further to the left and wish the raised foot were sharp. Maybe ISO 400 would have helped with that. Does it need a bit CW rotation?
