Great use of blue color scheme. The bright parts in the lower right along with the darker areas on the opposite side adds both contrast and depth, especially noticed directly under the wave in the middle. The movements of the water adds much fluency to it. You can feel the water surging towards the wave and the dynamic pose of the woman helps with that too. She and the dolphine are in focus while the outer objects such as the clouds and the birds are blurred out, kind of like a camera shooting them in fast speed, i find it very effectful. Great job.
