I think what the OP is saying is that the clouds above the snow were red and this red was being reflected by the snow. Therefore, this was, in his opinion, what the snow looked like. It would also reflect the weather conditions which is what he has been shortlisted for in a weather photo award.
Personally I prefer the first of the two images the OP posted. Would I have been tempted to neutralise the magenta/red a bit? Probably a tad, but not as much as you. Though it's nor my shot (more's the pity) and so my interpretation isn't the same
