Excellent work! The dock in the background should be a bit darker. I think the water movement around the dolphin looks great, but the boat splash could be a bit better. Try adding a LITTLE bit of noise around the edges to get some bubbles in there. Also, try playing around with some filters and maybe something cool might pop up which makes the splash look even more realistic. But I love what you did with the water around the dolphin. Looks great! Keep on Designing! -Adam
