Looks pretty nice. You may also want to take a look a Karro's WIP thread as he took (yet another ) of RobA's tutotial techniques to make his mountains and the results are quite good I must say. It all depends on the style you are looking for. I would highly suggest looking up DanChops technique in his WIP thread for the forests, using plasma noise. The results are great.
Open a new thread and keep posting your WIP's up for everyone to see!
