Very nice. I like the worm's eye view of the shot. Makes you feel as if you're a wee tiny thing in that environment. Nice and sinister/claustrophobic. Unfortunately, I have no experience with Photoshop whatsoever. I do tend to do drawings for NPCs, etc, and allow my players to bring in magazine or other clippings if they're not artistically inclined. And I've done floor plans on grid paper, but nothing nice for the outside of the buildings. That's a cool idea.
Also, something else that might be interesting to import into Photoshop-- Old photos that you can find in antique stores. I picked up a few daguerrotypes and tin photos from a shop around the corner for only a couple of bucks and if you're doing anything historically based, time travel or past life oriented, it makes a great prop. Very creepy, especially when some of them look faded or their eyes look strange.
Also, I checked out your Kult Klan site & really liked the idea of the architectural floor plans. That may prove to be a big help in future adventures.
You guys have had so many thought-provoking posts, I'm still paging through all of the ideas to see where my cosmology fits. I hadn't heard of Gaia (as relates to Kult) until recently, though.
