What I like most about the Nighthawk is that the wings are up.....a most unusual pose for the Nighthawk. I think this is the first image I've ever seen where the Nighthawk wasn't anything more than a "condensed mass of feathers with an eye" on a perch. An excellent capture.....especially in the eyes of a birder!!!!
I can't tell if the head is sharp--from the small size it's hard to judge, so please excuse me if I'm wrong. I would be tempted to suggest that you remove the weeds on either side of the post.
Agree with David on the weeds Difficult to tell on the head due to the bird coloring The pose is spectacular and intimacy way over the top One Killer image Big Congrats !!!
