Is that a 3D model? I ask because I'm seeing white pixels flickering along the edges of the dancer. Its as if she was captured to video while dancing in front of a white background with anti-aliasing on, then the video post-processed to turn all pure white pixels to black, leaving those pixels along the edges of the model that where some where between white and red.

It's good to see how high poly animated character models can be with Unity Actually I think it's an environment map with a thin highlighted area around the perimeter. This tends to accentuate the aliasing of the 3D model.
