Nice reflections and pose, there are some hot whites that could be recovered from the RAW, a better head angle and a lower angle from you would have improved this image a lot IMO. Congratulations!
I agree with Ramon re: HA and the whites, although they are close.
The shooting angle depends on what you want to display. If the nice reflection is important, then your shooting angle was fine. As you go lower, the reflection stretches and distorts, and loses its impact in the image.
Hi Brian - agree with Randy, heres one to try when you have a really strong reflection - forget about the bird and shoot the reflection only, then flip it up the right way in PP. Can be interesting :)
