What works: the sense of power in the down stroge of the wing; good head position; the displacement and spray of water all say power and force. Nits (please don't be offended): image could use a bit more contrast seems a little flat and soft; the BG is, as you already mentioned a bit distracting a masked layer with some gausian blur might help but then you would also blure the water drops: if you masked carefuly ( a lot of work though) it could be done. Nice image.
Wonderful action and timing Steve as well as excellent detail and exposure. I love the BG and how it brings in a bit of the environment and if were mine I would like to see a little more canvas on the left rather than an almost square crop. Congratulations and many thanks for sharing Steve.
