Well Whitney, I think your on the right track. I'm not sure by the photos exactly where you are quite yet, as the flesh tones look warm against the warmer colors and they look too "ashy" (gray and dry skin) against the cooler purple background. I would err on the side of keeping the browns to the warmer side personally. Remember that even dark complected skin will "tan" in heavy sun, and this guy should be seeing plenty of sun, so browns tending towards warmer tones would be most appropriate. Keep it up and let us know how it turns out!
