Thanks for doing that, Rob, and thanks for asking. I didn't need to scrape, as it turns out, and I went ahead and re-did the eyes so that they're closer to reality. I think it looks much better now and I'm very interested in hearing your take. I'm more comfortable (and better at) negotiating values but am still pretty intimidated by hues and saturation - color, generally, still freaks me out.
So post away, and thanks.
