I like the color balance in this photo and the exposure is great. I find that this photo may lack a definate point of focus. I know the frozen pond was meant to be a point of focus but it seems to centrally placed.
Despite the fact that it would be easy to mistake the frost for oversharpening halos, I think this picture still looks overshapened. It's an appealing scene that might be improved by not having the body of water in the center of the frame.
