Hi Giova, I like the soft light in this image, the low angle and the action. The bird is very tight in the frame and it will be much better with the birds running or facing to the photographer instead of running away. You have some cloning (?) marks near the wing tips and some kind of halo around the head.
Juan has covered it all . Really love the action you captured in this image and as mentioned if it had not been flying away from you it would be a much stronger capture.
