You might want to fix up those cliffs as they look really weird. Also, as others have pointed out in previous maps you shared on screenshot survival, I would heavily recommend making the tall grass darker. Map looks really nice though <3
I don't have a problem with the cliffs. The grass, you might have to edit the value and saturation of it but it still looks good. Mapping is great actually.
The edges of the river/water tiles look a bit too squarish near the top of the screenshot. The depth of the water also doesn't really make sense, as it appears to be more of a shallow pool?
I already have a dark green-grass tile. The criticism aimed in the screenshot thread was that the light green grass was too much of an eye-searing neon-green, so I toned down the colours to make it less harsh on the eyes.
