The sense of movement in here is great and I like the ripples around the immediate body of the bird but I find those peculiar blue streaks in the upper right distracting. I am not sure what they are... Other than that the composition could have been better by placing the bird (or cropping) a little from the left and a little from the top so the bird will more effectively appear to be heading diagonally into the lower right corner of the frame which gives it an enhanced sense of direction. The bird itself is sharp and well lit with a focused eye. The out of focus tail forks add to the interesting scene in the deep, refreshingly blue and cool water.
I like the angle and eye contact. I wouldn't mind if the 4 dark stripes above the head were not there. If you clone this should be relatively easy to fix.
