I'd lessen the trees a bit, spread them apart You used height very nice. But the rocks on the right side seem a little out of place. The moonlight is a nice addition but you overdid it a bit. The actuall textures are nice, and none look overused. Good Job overall.
Very good use of tiles and wc3 doodads. Good Job.
On the other hand it is pretty empty, and the trees all look the same :? more height variatons could do the trick.
