Sorry for the quick edit, but in looking back at the post, it was obvious I wasn't getting the detail In the wing and neck that I expected.
I rechecked the histogram, red channel, and was clipping, only in red channel. I did a few tweaks including decreasing the red sat. slightly, which eliminated the clipping. Hope this looks better, with more detail.
I agree with the need for more room at the bottom. I don't use photoshop yet, so don't have an easy mechanism for doing that. It is my list of things to do!
How difficult will it be to handle the reflections in the added canvas?
