Very nice, I love to ripple effect. The one thing I could point out is that the scale is just a bit funny in the picture, and without close studying it looks like the dome is just an underwtaer buoy or a piece of research equipment. Maybe it's the camera angle and the lighting. If you have a chance, play with the camera and see what you can come up with. Also, try dimming the lights as you go further away, and that will help with both depth-illusion and scale.
