Thanks for sharing this - it's nice to see a winter scene, and watercolour is the perfect medium for that. You've done well in handling the dark tones without them becoming muddy and losing transparency, which is not easy to achieve. If I was painting this scene I would keep the sky paler in tonal value to achieve a stronger contrast with the land, and consider using some broken brushstrokes instead of maskng fluid in places to create a more natural, broken edge to the areas of residual snow. Great work though.
