I don't mind the saturation but I would like you to level the "horizon" ie. the lines in the surf between colours as I find it really distracting and maybe crop a little off the forground deeper blue water.
The bird and it's pose are very nice. Is it running from predation do you think ? I have seen black necked storks here doing similar in freshwater when the big eels swim near them.
The Reddish at Ft DeSoto are a blast to watch and photo when they are in the mood to run, dance and fish.
This one looks like he is in that mood.
Not seeing the previous post I might be repeating, sorry..
I would straighten the tilt here, Even though it does change the angle of the Egret, that tilt on the beach is too far to the unnatural side for a DeSoto landscape.
Even though its a nice wing position, I think waiting just a hair longer would have gotten you a very nice head and eye position to match it. Looks like the eyes and face are a touch oof, so a bit of sharpening there may be needed.
Fun shot, I could fire off a card just on these guys fishing, dancing and running around DeSoto.
