This photo on its own would be a good shot. I like it very much for this challenge and movie title choice. I think maybe it would have been even better in monotone with a bluish tint.
A little obvious as a subject... the 'myst' on the river looks good, but the house is too dark and seems like a black void compared to the brightness of the rest of the picture (especially the overexposed snow in the middle).
The silhouetting of theat house/barn and the trees adds a sense of mystery, certainly, and I enjoy the light on the water, and in the smaller bushes. Slight downside: having to push the exposure as far as you have, some of that glare on the water is perhaps a bit strong? you composition is the weakest element of the image though: i can't see that lifting the camera a touch would have harmed the exposure - though I suppose the sun might have begun to flare - but the very bottom part of frame seems to add little, and the cutting off of the trees at the top does harm things: and especially when you end up with that building placed a little weak in frame.
