It's a nice environment and nice to get the action. I think I'd crop the tan area on the right or color it green. You might want to revisit the highlights in raw conversion -- the feathers under the wing don't show much detail -- blown out? Or just no texture there? You might consider cloning out the leaf coming in from the bottom center, too.
Good you got a clean view with no OOF stuff in the way. Not easy in a place like this.
Some other touch up worked I'd do is, after you crop like Diane suggested, take
the tips of the grass that are brown, and make them green like the rest of the
grass.
Not sure on how to handle that long blade of grass that's brown though. If you
'green' it, the intersecting lines might be to much. Removing it is an option, but
might be tough. Or just leave it as is.
