I've been working on this off and on for a week or two, now. You know, I didn't have to put in multiple light sources. Which then leads one to the perfectly reasonable question as to why I did.
It seemed like a good idea at the time. At least until I realized it basically meant doing a full set of shading several times.
Anyways, enjoy!

The energy to this is fantastic, what fun. And egads the lighting...tricky stuff and so wonderfully captured!
