Any ideas for making this look less sketch? :D

Just looking for less clash, somehow make this look like it's supposed to be there. (which it is )

See terain's tutorials, you will quickly learn how to create some cool stuff by yourself.

Its important to remember of don't create a place just with one kind of terrain, like Grass, mix them a little, but not too much. Avoid creating random terrains like Rough Dirt inside grass, or Dark Grass inside Dirt. Try to create a main path with Grassy Dirt. Doodads are also very important.

Good luck with the terrain.
