Hello, so here some improvings for you;

- the mountain tile looks terrible - its flying over the water.

- right side, the grass on the sand, dunno may hold it away from the mountains

- the center part - the path tile is at the end just "broken"

- the "bridge-tile" - may you find a better one?

- shadows ... if you use a shadow for the little sign, then why not for the other parts?

- top part - the way tile is directly binding to the water-edge - iyou can see 2 pixel ground texture - doesnt look good for me



So ill hope this helps you!
