Nicely done Tom. Excellent underwing detail and fully sharp on the bird. Good comp. The only thing I would play with a bit in post is that I might try to tone down the brightest bit of background and it's reflection a bit to about the same brightness as the remainder of the background.
The herd behind is part of the 7,000 or so Sandhill Cranes that can be found here in the winter. Amazingly few people know of this place near Chattanooga Tn.
