That looks very good. The colors and lighting are really sweet. Great work on that.
The stones are a bit big, but they still fit very well. Also, good displacements on them!
The crystal clear water and reflections look great too.
Really looking foward to see where this is going.
Can you give some more renderspecs? I think the scene could benefit from some more atmosamples, but I think they are already set at 64 at least.
Probably takes quite some time to render this
