Your cliffs are almost completely wrong, there's way too much detail, you don't know how to connect tiled trees so you use NPC trees which are ugly, the waterfall/river is poorly tiled and the caves don't look very good either.

I'm sorry, but it gets a 2/10 for effort, but no more... try reading some tutorials or something, I believe there are some stickied on this forum (though I could be mistaken)
