Hey there!

So firstly, your terrain. It's completely flat, minus a pond and a small cave round the back. I understand that the majority of this plot is covered by the structure, but that doesn't mean you can't have some layers of grass under and around the building.

Secondly, your organics. I like the shape of it; it's very unusual, but it works. I'd suggest maybe a few more leaves a little further down the tree, just because it looks like a sudden change.

Lastly, your structure. This could have easily had depth if you'd have done something like this with the quarts:

(Of course imagining the logs were quarts, and the wool was brick)
This adds a simple amount of depth, and it's a small change but it changes the building so much - for the better! That would make the outside of the building appear much more detailed. I can see you have building skill, you have a good eye for creativity in structure and shape of things, it's just finer details that need adjusting.
If you apply that change, you can add some detailing with the use of stairs/slabs maybe; quarts? Just subtly placed to add to the build :D
You build is edging on the modern side, which we normally don't accept, but this has potential to show detailing, which a lot of modern builds don't.
Also, I like the interior :p Very stylish!

Good luck!
