My favorite mountains are done by Pasis. Here is the link to his Rising Up the Mountains thread: http://www.cartographersguild.com/tu...photoshop.html The last PDF document in the thread has the best stuff.

Ascension has also done some amazing work. I am very fond of his Planet Making tutorial ( http://www.cartographersguild.com/tu...photoshop.html ). A Continent tutorial ( http://www.cartographersguild.com/tu...photoshop.html ) expands upon those concepts. And those are only two of his tutorials. He's also done town tutorials.

Look up tutorials on Eriond and Saderan. I can't recall off-hand who wrote them, but the results are gorgeous as well.

I'm afraid I mostly use GIMP, so most of the tutorials I follow are from the authors of GIMP tutorials. Sorry if you've posted a PS tutorial and I've excluded you.

Good luck Entity of Sin. Hope you find what you are looking for.
