Fantastic article, TMDI! It taught me how not to do the one thing I always do to screw this up: I always start from the inside out. No wonder I have so many problems!
Plus, I like that you separated out the fact that you're using the 2nd darkest color for antialiasing and for shadows. It's a subtlety that I think I've missed on more than one occasion.
@Keeth: I know everyone always equates art with talent (even teachers, sadly). BS. If you have two working eyeballs, you're most of the way there. Practice is the sucky part.
@Abhishake: That does seem like a wierd phrase. Will change, and thanks!
@LJR: There are some really great tutorials on st0vens site and mark's site. It's a very strange technique which isn't really intuitive. I still struggle with it constantly.
@Xeallllll: Our love must forever be forbidden.
@Evi: Thanks! Would you throw up another challenge? I'm having a hard time coming up with a good idea for one.
Or you could just use dream maker's arrows and press up and to the left one time each when you're done..then edit them accordingly to that so they line up easier. That's the way I do mine and they come out very good.
My results from this technique are now posted at Dungeon Crawlers. I also varied the rock colors between medium, light, and dark, using a range of 6 colors instead of 4.
