Carl:
Good looking falcon, great eye contact, feet. Well exposed.
The light angle has cast the underwing areas in shadow. In many cases, over your shoulder works best to fully illuminate the subject.
Because of the direction of flight, I would be inclined to give him a bit more space to the left.
Nice first post, welcome to BPN, a great place to learn and grow!
Love the flight pose given by the bird, I get a sense of speed from it. Normally I prefer full wing stretch, wing up or down but this pose works for me too. Also like the determination look in the eye of the bird and your bird looks sharp with good detail too. Wish the wings are more evenly lit.
