I have two 1: 6 scale predator figures by Hot Toys. I photographed them in the pose you can see here- using little cheap led head-torches to create areas of detail. Camera was on a tripod with a 10second exposure in a near pitch-black room. I removed the original background and used one that was in keeping with the predators. Then added some mystical lighting, painted some green blood, and added the rain. Then I took a tilt-shift effect to focus on a "slice" of the image. Finished off with a dark vignette. Done with CS5.
Hope that helps..
