You know, I think it's perfect, but then that's just silly me...
I think it's absolutely charming. Everything is good. Maybe the textures don't match each other perfectly in terms of styles, and there are a couple other things, but it still looks perfect to me. Good job.
The hills are cool... so cartoony.
Perfect doesn't mean it couldn't be better; just means that I subjectively don't think it deserves too much criticism, because it's a simple, plain, good scene with a rare simple crazy style AKA perfect. I hope to see you moving in that direction; that'd be cool.
