I'll try to fix edges and edit it later.

Sweet! I love the water edges :)

Make the edges wavey, not straight. It works wonders.

There's some nice details here. The water is quite good as is the sand and rock/ground.

I think the trees and bushes do not fit the style of the rest though.

I know, but idk how to do it :D

Your textures are really nice, I do think that the transitions between tiles could be better though.
