David,
Magnificent flight pose captured. Love the pose,nice details and colors.
I like the way bird pops on on BG.Wish some more space in front of bird. For my personal test crop is bit tight.
Your only images of this species and they are flight ones, awesome! Nice details and overall pose. I also like the texture of the water. Too bad the near wing is not better illuminated, but man I'd be very happy with this.
