Anyway, let me know your thoughts and suggestions.

I think the house itself looks quite nice! But the environment around it is a bit bare and lacking by comparison, and I think the trees and bushes are a bit poorly shaded. Instead of just making a big blob with bands of light and shadow, breaking up the canopies into smaller chunks and adjusting the lighting to better reflect their 3d form would probably help.

You’re obviously going for a very stylized look, so you don’t need to go all the way with the rendering or detailing (For instance, the trunks are fine for the aesthetic you’ve chosen), but I think referencing how light strikes real-life canopies (perhaps you can try with more “top-heavy” trees like rubber trees and baobabs) could help inspire some big improvements to the foliage.

Anyway, sorry for the big wall! As I said before I think the house itself is good, so I have no doubt the rest will be fine if you give it another pass or two. I’d offer some more concrete suggestions, but sadly I can’t draw rn due to an injury.
