Cool Tilt... I hate to say this now that you spent all of the time, but most of the mountains look like pyramids. Not that it's horrible or anything, but I figure if your hand drawing all of them, you might want a bit more variety in shape to make them stand apart from each other. One "good" one is in the middle of the horizontal run, there is a largish mountain that's got a nice big crack in the "light" side. It would help to have some "jaggies" or cracks on the perspective line forming the "front" of the mountain and likewise on the back right edge on occasion.
