I like the idea and everything, but I don't believe it was well executed.
It's extremely visible you only used WE for your build, something that's not recommended when building mountains, cliffs, structures, etc.
There was needed some human touch and some //brush smooth work, and I don't like the use of both snow and ice for the floor.
The candy cane doesn't look great and needs some work, and the whole area by itself is completely empty as well as the air.
I'd suggest filling out the empty space with some houses, maybe snowmen, more candy cane (not pixel art), path walks, and more.
I'd also advise you to fill out the air a little bit with some animals and maybe snowflakes even.
