It is a bit centered compositionally but I guess that couldn't be helped because you needed to get that church in. Only you know what was either side to decide whether you could compose it differently.
Rule of thirds is about right.
Exposure is nice and clean although if it were mine, I'd try and take some of the blue out of the shadows in the foreground.
One thing I would say is that everyone takes their pictures standing up straight so this kind of shot becomes a snapshot because 99 out of a hundred would take that picture the same way. The saving grace of this particular shot is the shadows and footprints in the foreground giving some contrast and depth, without them all that whiteness would make the picture look one dimensional. Always take shots from different perspectives, that makes you the one person out of a hundred who takes a different picture than anyone else. In this case for example, you could have got on the ground and shot across the snow (if the ground is too cold/wet, get your boyfriend/husband to lay down and use him as a mattress
).
Look at the objective as taking ten shots to get the best shot as opposed to trying to get the best shot every time.
