Thinking about Peter's comments, I tweaked it a bit, and added a wrinkle or two.
Pulled down the midtones just a bit, the slight darkening gave a little more color to the plumage and made the water pop off the darker blue water.
Sharpened the splash and eye selectively. I think overall sharpening as mentioned by Peter would work well, but I wanted to really draw attention to the splash.
Thanks for all the comments and the repost by Randy. I think the new version is a big improvement (I wish I'd thought of doing that!). I find this is one of the most difficult things about this form of art that we are all so interested in and passionate about- seeing the detail in your own images and thinking about them out of the "straight-jacket" of ownership, as if they were produced by someone else.
