Hey there! :3

Your plot feels very unfinished. As you have a nice looking bit of terrain on one side of the plot, and then the other side is completely flat - please make your terrain consistent; the snow/ice terrain looks lovely!

The various glass 'organics' you've made don't really work on the plot, and I'm a little unsure of what they're supposed to represent.
The house also lacks a huge amount of depth and detail, and isn't very interesting to look at. I'd start with a frame:

That's a nice/simple way to add basic depth, and it also makes it easier to detail.

I think you need to finish the plot a little more than you have here - fill all the gaps - make your terrain all just like the snow/ice terrain - add some more trees, they're really cute! - add some detailing/depth to the structure.

Good luck!
