I love reflection photos. You have the right elements here and the correct colors in the proper proportions. Your timing is also impeccable since there doesn't seem to be a drop of wind, which is the best time for a reflection photo.
That being said, I also have the following comments. There seems to be too much sky. My Caedes friends are always telling me to keep the sky minimized unless it adds great drama to the shot. Since there are few clouds of any kind, no lightening, no sunset reflections off the clouds, I'd cut back on the sky by 50%. I don't like all that negative space in the foreground. It's just dark matter with little shape to it. If there were pine trees or recognizable shapes, I'd keep the dark foreground in the shot. Finally, and I don't think you can do anything about this, but I think the stuff floating out there in the water is distracting. Anyway, that's my two cents.

I think this is beautiful just the way it is. The grass in the front gives such lovely depth to the whole thing, expanding it all. It's wonderful. Verena
