This picture has a lot going for it. Great color, great exposure. The DOF (one of the hardest things to get, I think) is nearly spot on.
The problem for me? This photo is a good example of the application of the rule of thirds, but if I didn't know the title of the challenge, I wouldn't be able to discern it from your picture. Yes, it's an example of ROT (and a good one) but it's not THE rot. Hopefully that makes sense.
7 - Amusing title and good meeting of Challenge. Criticism; difficult, as you have applied the rule well in my opinion, although I am no expert, in regards to the Challenge. However, given the subject, I just wish the wings were not cropped. The colors are nice, the background is a little detracting though in my opinion, just a bit 'busy' for the subject(s). Maybe just a straightening/rotate, especially if you are going to 'chop the wings', retain or 'use' the symmetry to 'balance' the shot, not sure.
