lounging water dragon

It's a water dragon that's lounging on some coral. I tried to do that effect where the water has reflections underneath, but it didn't work out so well. the reason the dragon's belly is that bright color is because it's camoflauge is like a penguin's. from below, since it lives in coral reefs, it's belly is bright red so that you think your just looking at coral. From above since the ocean is dark it has multicolored smooth skin so you think your still looking at water. Complicated, huh? Oh well, i tried. enjoy.
