You caught this guy at the peak of the perfect "umbrella pose".
I like the curtain of water trailing behind the leg as well.
IQ is excellent and the whites are well exposed. I do see a very slight yellow/?green cast to the whites and if this was the way the light colored his feathers that is fine. But I would be tempted to go to color balance in Photoshop and reduce the yellow by 1 point.
I would also evict the bright highlights in the water below the egret and the big specular highlight in the wave on the right.
Love you low POV. It feels like you were almost under the umbrella,

The pose is perfect, any one who has watched them fish would know what they are doing so the story is so clearly captured in the pic
Love the quality of the image, agree with gail on removing those highlights it would take up the image a notch
