A very nice adaptation. Thanks for sharing.
I'm working on some shaded PNG versions of Ramah's awesome mountains, that were made into PS brushes by vhailor27:
Mountain brushes from Ramah's Aronbor map
I'm not planning on using all of them for my map, but I really liked how they turned out, so if there's any interest in them, I'd be happy to go ahead and do the whole set.
Since both Ramah and vhailor have said they are fine with commercial use, I'd be happy to do the same.
These are the first 20 I've made so far, shown at 50% resolution.
