Nice, solid image of this egret.
Whites look good.
The tip of the tail is very close to the edge so if you have a bit more room I would include it.
If this was mine, I would clone out the ?rock to the left of the bird in the water and I would clone in green vegetation at the top of the frame where the white area is above the head.
Did you get a vertical? That would look nice as well and give you room for the virtual feet underwater,
