1st off, loving the Slade references!!!
Fantastic photos, and if you look at his 'about me' page, he is only 29 (B*****D!)
Anyway, looking at the light in the pictures and when you look at the behind the scenes section you can see he uses a lot of lights, be it in the studio or on location. I'm sure everything is carefully planned to start with by himself and an art director and then long days refining the concept and lighting. He uses a mixture of natural, studio and ring flash and compositing of shots in post too. I also think he may use an element of HDR in his post workflow - if you compare the textures he achieves with some of Valdore's work (check the HDR thread in this forum) you will see similarities. I'd say he is shooting medium format too, in order to get such detail and texture in the shots (and just because setting up such shoots costs so much anyway, what the heck!)
