There isn't anything complicated going on with lighting there, that's just two point lights (same as pretty much all my recent renders).  This environment prop is the big secret:

Spheres work too, just this kind of environment mimics a photo studio fairly well for GI / Indirect Lighting purposes.  For the earlier renders in this thread (the super-bright ones) I had two point lights set for Constant attenuation, for the later ones (and probably most future ones because I'm getting more comfortable with it) I set the lights to Inverse Square attenuation.  No "cheat" lights or infinites or anything like that, this is plain old "practical" lighting that you could reproduce with real lights.  My render settings are actually terribly low (irradiance caching 1, IDL quality 1) because I don't feel like waiting all day for essentially a one-off forum render.

The black boots are some pretty nice ones by Idler168 - I think I want to start modeling and rigging more shoes of my own though, I only have a couple that I've done and they're very unique (the white backless thigh boots and the crazy wraparound Arcane Edge boots).

Thanks for the flattering comments :)
