Mike,
Did a great job on hiding the fact that you shot through a window. Absolutely could not tell. The "catch" is a good one too - that is, the bird isn't just sitting there. He is in an interesting pose.
Couple things, though: First, the crop seems like it would be more effective it it were a little bit tighter. However, I am not going to edit that - how you want to frame is your call. The other thing is this: At least to my eyes, the color cast you chose to go with does not seem to compliment the subject. Too cold - too much cyan.
With this edit I altered the color cast by using Curves/Set Grey Point and setting an area of the white wing. I then bumped the contrast and density by duplicating the layer and blended it at Soft Light. The background seemed a smidgen grainy, so I selected the background and Gaussian Blurred it only 2 pixels. Just enough to smear out the grain - without adding any bokeh. Wile I had it selected, I desaturated it about 35%, to help focus attention on the bird.
I hope that I did not kill your intent in doing so, but, as a viewer this is easier on the eyes than yours.
