Hey there :3

Firstly, terrain. I really like your terrain; the details, the layers - I can't fault it, good work.

Organics; I would thin out the trunks just a little, if I were you.
That, or I'd bring the leaves out a bit, maybe add some branches too to make it easier :p

Lastly, structure. I like it a lot! I love the detailing, and you've got a really nice palette. The only thing I think needs fixing on it is the roof. Instead, I'd use full blocks instead of stairs. Maybe make it along the lines of this: https://imgur.com/a/Lr9Ab#0
Don't copy it exactly, but use inspiration from it - it's the same style as your house ^.^

Good luck!
