Looks like the cloudy sky fooled your camera's exposure. this needs to be brightened by a minimum of two stops. Too bad too, cuz the the crop and composition are quite good.
Wow. I like the placement of the pictuer. I love the hand and "look" of the falcon. I wish it were a bit brighter, with more picture over the head of the falcon. Having the head at the very top makes the picture look cramped. I really like this shot.
I would have liked to seen more sky in this photo. I think it would have added a lot to it. Instead of a square image you'd have a more appealing image. The brown goes extremely well against the grey sky but the ruffled feathers from the wind gives it an OoF appearence. I also find there to be to much glove but that could have been corrcted with more sky. Good luck in this challenge. <5>
