I've been mapping for a few months now. The only problems I've had during my process of teaching myself I encountered were complex displacements and making my own models.
After reading this and trying it out...It worked perfectly. I'm very happy :]
Have some questions for you
sometimes when you align multiple brushes and corner them to be ready. when you turn them into displacements their "grids" do not align. (I'll get a picture) This usually causes difficulties in forming your displacement and painting on the alpha. Anyway to get around this?

also if you wanted to have a top of your cliff that you have made. How would you do this? just make brushes to fit over the surface and make sure they align with the sides? will the grids be misplaced in this case and cause problems?
Great tutorial. I'd love to see more :] and any help is greatly appreciated! ^__^
