Hey there :3

So firstly, your terrain. You have a nice variation of layers - you have a nice raised area where you've 'decorated' the land, and it looks really nice. The area where you have the house is flat, but its covered so it looks okay, however next time I would suggest building some more layers under structure.

Secondly, organics. I like the trees, however could you build some standing up too?cx It shows more creativity if you can build a tree with roots, branches, and full leaves.

Lastly, your structure. It's an okay design, you have the logs in the right place creating some contrast, however the block types are all the same.
Firstly, I'd suggest making the roof a different block type to the wall block. I think you need it to overhang the walls, so that it's not on the same layer as the wall, and doesn't blend with it.
Next, I think you'll want to move the logs out one layer - this creates basic depth: https://imgur.com/ONsoRxh
It'll also help you to detail. A house like this, you could use stairs, fences and trapdoors to detail the walls.

Good luck!
