This photo received a pretty decent score overall, so you should be fairly satisfied. I believe it scored just about right.
In order to score a bit higher, I think there are a few things that you could have done that would have improved it. First of all, lose the border (or at least reduce the size of it). For a picture such as this, which has delicate colours, the border is a bit heavy. It draws the eye away from the main focal point. It may only be a sub-conscious thing, but I think sometimes borders can hurt the score in a challenge.
MaryO already touched on this in her comment, but I do feel the composition is lacking a little. The horizon, or at least the fence which is where the eye goes to, is more or less centered and this could be improved a little.
For my taste, the colours are also slightly over saturated. However, I think this may just be a personal taste thing for me. (I would love to see it in Black and White).
Overall, I think this is a good photo that met the challenge, but with a few small adjustments could have scored slightly higher than it did.
Blue tones certainly make this feel very cold and the leading line of ski tracks pulls me in. Composition feels a little off to me, though, like it could use more foreground so it didn't feel split half and half sky and ground.
Wow, the brightness in this actually made my eyes hurt for a second! :) I love the colours and the tracks in the snow - especially as they lead back from the tree. Nicely done.
