Like Drae says above. The Stone Path doesn't look right - try another path-type tile(s). The staircase would look better without those side banisters. The entrance/exit to the cave doesn't have the right color tiles (There should be dark tiles that color that are meant for that entrance). I'm not sure what, but you should do something with the side of the mountain. Maybe a little platform of grass jutting out, that players can jump down to? Or some more foliage to cover the mountainside (Gfx). But does look nice
