Just thinking, a lot of your environments seems to have a "cave" like quality to them. There is layers and layers of accumulated material, hanging structures, pillars, columns of light coming from unseen openings. They are very heavy with texture, and I think it makes them gorgeous. Heck, even your caves look like caves!
Maybe cave isn't the right word, but you do create a lot of enclosed, or sequestered environments, with very dramatic light and shadows. I really enjoy your work, and this one is probably one of my favorites.
