Use the tree tiles, those treetop NPCs arn't needed.
The path just seems to stop, at least connect the 2 ends up.
Fix the cliffs, there are tiles that go at the top of them to fit in with what you have done with the diagonal cliffs.
Lots of small tile errors around the lake that need to be fixed.
Waterfall starts way to high up and untill it hits the cliff it looks really bad using the bottom of it for the top.
Grass needs more detail.
House could use a little work too so it doesn't look so plain.
Water detailing is okay though.
