Nice shot - I like the variance in movements of the water and the injection of green from the seaweed below. What is also good about the composition is the depth of detail i.e the rolling wave and birds towards the background. The soft pink lighting coming across from the left it also great.

Now I don't know if this is just me but is the horizon not quite straight? Seems to drop to the right but may just be an illusion. Otherwise a fantastic shot.
