Harry, I like the shot very much, wings, legs position.
Suggestions. Cropping is a bit too tight, I would add more on the bottom as this is a landing shot. Also, the forehead and neck, white is overexposed, see if you could pull some more details back.
One more of favorite birds to photograph.
Harry nice flight shot. The bird appears to be a little over saturated as the wings have a purple cast to them. I know most photographers like to see this bird really pink and make the mistake of apply the saturation a little to heavy on this bird. Just a thought and keep shooting
