Phew, this one took a while!
This is in Cycles, The only thing that isn't mine in this image is the head model, courtesy of Hammerh5 at blendswap here: http://www.blendswap.com/blends/view/66590
Textures, lighting, materials, everything else is mine.
My favorite part about this, I think, is that this render is only 500 passes.
Even though this says "Finished", I'll probably reupload a new version as I tweak some more settings.
