I love the white bird in the middle of all those deep, dark tones, Fabs. I might be so bold as to suggest toning down the one brighter plant in the BG as it's pulling my eye away from the bird. Really nice blur and great comp.
Agree with Jules that the plants at the top distract from the egret and could be toned down. They reflect in the water so you can't go too far... Love the colors in the water.
