For a Haiku this is okay, but the trick to a good haiku (in this case) would be not to focus so much on what the snow is doing but how it looks. Maybe even a metaphor in there.

I liked this Haiku. It sounds good to me. Good one.

Well, i think you did a fantastic job here, especially the effect of the third line contrary on what Ether said. The image was so clear and i can actually visualize the mountains so white..hahah..Good job..5/5

Word choice could have been better I think otherwise I liked it.
