Okay so basically I am trying to make this one in two versions, a sketch looking version, and a painted terrain version, so far... even though I have the most beautiful brushes I have ever seen... my mountains look like crap.

The idea is the keep is supposed to be surrounded on almost all sides, with a small open area for a river... but it looks exactly like what I did, randomly put mountains around it... so how do I make this look natural and not random?
