Good image, I especially like how you have captured the movement in the water, but I think the reason the image might look a little unbalanced to the previous viewers, is that the bottom left hand corner third seems to me to be about a stop or two darker than the rest of the image and so draws the viewers eyes straight into it.
Try lightening that part of the image to balance the light across the scene more evenly and I would even go that bit further and also bring out the colour of the grass/seaweed to make it a feature the viewers eye can rest on, rather than being half hidden by the darkness of the water.
