You have exposed the colours nicely. This is sharp, and I agree with Axel regarding a rotation. In addition, I would take a bit off the bottom, and add a bit more to the RHS.
I also love the painted effect. It would be nice if the whole reflection was showing at the bottom, otherwise crop some more off as has been said.
cheers
This shot really takes my breath away. The colors are incredible. Great sharpness. Wonderful light. Only critique - maybe slightly more room to the right.
