>>22502388you should probably elevate the red circled islands more, the Mart should be swapped with the yellow circled house (who would build their Pokémart that far away from the Pokémon Center and so isolated from the rest of the buildings?)
The green circled shore looks meh, you should use the tile that blends more with the sea, after all it's a beach.
The fence on the sides also doesn't make much sense, put some rocks there instead.
And the tile for the paths looks really bad and disconnected, isn't there a better looking tile for that?
That aside, it's pretty good.
