Nice wing, tail and head position. A bit soft on my monitor, perhaps another round of sharpening. Including the technical details of shot always help us critique.
Might be able to brighten the eye a bit, with a bit more contrast to help it pop.
Great flight pose and I love the out stretched wings. It appears to be a tad soft on my computer. A tad more canvas on top and bottom and less on the left would off center the hawk. Many thanks for sharing Phil.
