It's going to be a nice (final) render eventually, I'm sure, but I think the POV doesn't work very well. Somehow there is very little depth in this image probably because of it.
I also like that funny outcrop on the left thing

So practically I would elevate the camera some, or move it behind that ground swell in the foreground. I don't know, I think you'll have to experiment a little, if you are still open to changing the POV.
