This is very cool! Aside from the vignetting, what PP was done for this?
Well, it's a series of very small adjustments. Before any pp, in-camera matters a lot. Lit the scene with four strobes, except I only had three lights so the the interior window was lit in a later shot. A fog machine was used under the porch above a strobe to diffuse the light coming out of the hole. A warmtone umbrella was used camera-left, while a 20 degree grid spot was used camera right, pointing directly at subject's face.
Post consisted of blending black and white into color, using shadow-highlight to pull micro contrast out, and then color tinting. Overall coolness, then warming the hands. Subtle hints of contrasting red and green show up. I did a dancing game going from lower right to upper left, keeping the colors contrasted while editing.
Here's a comparison...
