The colors are spectacular! That is one of the most beautiful reflection I have ever seen! The only way I could see to improve it would be to get the top of the trees in the frame; but that probably is unrealistic.
Beautiful colors, although I have to say for me, it might be a little on the strong side. Also something about the crop is bothering me ... maybe the three trees needs some breathing room on the left? Looks like a very peaceful place.
