Sure, let me see -- here's a couple of different styles on an island map. The first one shows the eroded cliff style brush, and the second one shows the skinny ridge brush along with some buttes. One thing I'm noticing is that while the brushes do okay with laying out "sausage strings" of mountains, if you want to get precise placement you're probably going to have to nudge some of your mountains by hand. In the case of the long peninsular "tail" of my island, some of the things I did were:

1. Using the lasso to select mountains that ended up in the wrong place, and using Free Transform to nudge and rotate them until they lined up correctly.
2. Painting a few different types of buttes and mountains in a clump, then using the eraser, also set to one of the butte shapes, to randomly "eat into" the clump and make it look a little less computery.
