Not bad as far as the cliffwork is concerned, but I don't like the half-sized cliff on the top left. Your paths are good but a bit basic, you could try and mix them up and make them look a bit more rough if you wanted. The biggest problem I see is your detail - I think you need to clump things far more and add some more grass tiles.

Otherwise it's a great start, if I were rating it I'd give it a solid 7/10 if you rarely (or never) make levels.
