This is a test render using Powerage's Powertown sunlight lighting setup which predates Superfly. I should use something more modern.

The change in skin tone was done by adding C8937B to the alternate specular on all 4 skin materials, and the eyes had some other color I didn't memorize added to the alternate specular. I do notice how glassy the eye surface is and wonder if that's the lighting designed for Firefly at work here.
