I think it is pretty lovely as it is! In a perfect world you could ask for a few more puffy clouds nicely balanced across the sky. And waiting for the sun to come up a touch more and give that nice sunburst effect might make it more dramatic. But I think the composition is pretty nice, the foreground is interesting with nice texture. I'm a dead tree guy so i'd perhaps pan a tiny bit to the left to get more of that, but it is working well as it is... I think the slow shutter speed to smooth the water is quite effective...
Nicely seen and executed.
