Well, after thinking, this isn't very good:
1. Bridge looks way to cramped and tiny, you can jump across that river.
2. The trees in the forest aren't spaced apart well enough-if you're gonna use dem trees, at-least use them correctly.
3. Lack of detail, could use some stone paths, plants, and maybe some low brick walls surrounding a little town.
Just take everyone's advice and this'll be good.
But the cave is very good, and the layers are good- the way you made the sand and grass.
