You do what I used to do when making paths and whatnot; overusing the diagnal tiles and not enough straight tiles. You'll need to stop that.

The one tree that you extended looks horrible, please downsize x-x.

When you use the layered grass tiles, make it intermediately stop, don't box in an area with them, it sort of seperates parts of a level when you do so.

You'll need to show more of what you can do with sand paths, but I noticed you forget to add in the 'closing' tiles more often than not when you make sand paths.

I suggest detailing the grass, the sand tiles, the water, etc.
