Looks very good, the yellows are nicely exposed. I might give it more room at the bottom to include the complete flower on the left. The catchlight is quite low. Did you use flash?
i love the environment here!! really cool with the extra flowers. a little extra on the bottom to include the entire flower on the left corner would be perfect!
Another striking image, Mike. My minor comments have already been mentioned above - the clipped flower in the LLC, the dark background blending with the bird's head, and the eye that appears to have multiple catchlights. A little tweaking would likely take care of those issues. Another possible presentation might be to remove the 2 flowers on the left and crop it as a vertical if you have enough pixels to work with.
Lovely enviromental image Mike, and I like the colours in this. I feel the darker BG works, as it makes the subject stand out much better. Well captured.
