Thought again to make a fantasy scene :P Used the perspective transformation tool to posionate the water a bit lower. The rainbow is made usind the special gradient option set on overlay and on rainbow style. I cut of the ball using the patch tool. The rest is made with blending options, contrast tool ad dodge and burn tool. More in SBS. Enjoy!
