My impressions (keep in mind I'm a novice):
- Needs consistency in detail lines... on the far left, horizontal and diagonal board beneath the upper window has detail lines, but the lower window's counterparts don't.
- I feel like I'm noticing the foreground vertical wood pillar too much, like it's too contrasty considering it's in shadow.
- The roof at the top of the leftmost building looks like it doesn't follow perspective, and it's slanting "down" towards us and to the left too much.
- I'm not sure what the roof textures are supposed to be... the lines feel too haphazard to be shingles or something.
- The roof of the center building (shaded at top, comes into sunlight as it curves to center frame) looks like it's paper thin because there's no vertical definition at the end.
- The grass on the background hill seems too detailed considering how far away it is.
To build on that last one, a common trick for perspective is to fade-out or reduce detail on objects that are further away from the camera in a picture.
I'd also try and simplify the post near the camera, the focus on the piece seems to be the village.
Normally to accomplish this you'd blur the foreground object (as seen in this picture here) to help guide focus,
but that isn't exactly a technique built for pixel art and I'm not sure it would help much in this instance. Instead, I'd reduce detail and maybe tweak it like this, so that it's also simplified, to sort of "emulate" the blur without actually drawing said blur!
