I liked what you tried to do with this shot so I tried some PS tools to see what could be done about the exposure problem.
1. Used the burn and dodge tools to even out the most extreme bits of under and over exposure.
2. The round rock left foreground was so overexposed I could not do anything with it so I used the clone tool to cover it with moss. I also used the clone tool to cover other little bits of overexposure.
3. Selected the water and adjusted levels a little.
It's still not perfect but to my eye it's an improvement. I hope you don't mind me doing this.
