Thanks for the compliments and the suggestions. I added some shadowing for the mountains and also slightly softened the edges of the sphere and model. I don't believe that you would find more defined shadows on such turbulent waters as these. It was a specific choice I made not to have them defined so they looked more natural. At least that's how I see it. The choice of texture was to make her look like she was made partly of water and also so it just wasn't a nude woman on water. Nammu was part of the sea and that's what I wanted to portray.

I still don't see shadows of the mountains on the water. The rest is better.

Hopefully they are a bit more defined now.

Thanks!
