Nice timing, fine wing position. The HA looks pretty good to me.
I agree with Joe about toning down the rocks a bit. I might also remove the one dark stick pointing up beneath the birds wings, and consider a small crop, about 20% of the free space, down from the top. To my eye it helps work the diagonal a bit more. All the action is down towards the left, so I am thinking that the space above doesn't add too much. Purely personal taste.
