The hue is different on both side of the face. The right side looks illuminated with gels or halogens whereas the left side doesn't. I'd either tone down the gel colour on the one side or reflect more of it on the left to balance it out.
Because of the blue background, it actually looks like a hot/cold image with the colour gradient traversing the image.
