The first image I felt I can show publically. A sea, 5 radial lights, a terrain and a sky. I was happy to see that waterfall effect which was a fluke, but then I enhanced it by putting some negative lights in the sea, so as to create some contrast. I would more than welcome comments and suggestions for improvement.

Good Job.

Looks good.. If you wanna decorate it up a little..? I would add some foliage, trees, rocks, things like that on the upper terace... Maybe some more clouds in the sky, and I think I would play with some mist, or vapor on the main body of water.. Also if there is a way to get the last terrace to flow down to the main body of water that would add a lot. Hope that helps
