Very nice. The one thing would say (and this will sound stupid) is that the sky is a little black. Maybe if you could have blended a longer exposure and tried to get some stars or something into the sky it might have been better.
The reflections in the water are very good and I love the Christmass tree but I do think because of the angle that you took the shot at the LHS of the shot gets very cluttered. Its kind of hard to look there and pick out the individual detail. Probably easier at a larger resolution but a bit too cluttered at this resolution anyways.
