we need more purple

Very nice. If her eyes were more obscured, this could pass for real. Great job. I remember from Avatar that they said that making the real scenes a little softer and more surreal made the cg parts seem more real by comparison, and I think you have found this balance here: that staged/affected-popstar look and pose, the very real skin, the very fake hair color, the professional studio lighting, it just looks airbrushed. Really great job.
