Fabulous splash. For me, this is a case where the dark image works to advantage, although a little brightness in the eye might help. What is the species?
This is quite a strong and unique image. The splash is amazing, and you caught the bird at the perfect time. I'm not thinking the image is too dark b/c your whites on the duck's wing are just right. I would love to see a little more light in the eye if it's at all possible. I think it would bring even more life to the image.
