We have an invasion of red footed falcons lately in the Netherlands. These birds normally live in Hungary and other Balkan states in East South Europe.
I don't mind the composition and framing. I do find the Hawk too small in the frame allowing your perch to be very dominant. I would also add a little more sharpening.
I agree with Dave...I would personally remove about 40% off of the empty space above. And I agree with Dan and Maxis about sharpening. Looks like its dining on a dragonfly?
