Really, really like this shot. Only thing I find distracting is the bright red cheek on the right. I would tone it down and soften it a bit. Just a quick PS to give you an idea.
the thumbnail seemed interesting,but i like the opened photo even more! very nice shooting angle,beautiful expressive face,effective lighting and tasteful photoart. my only objection is the harshly cropped chin,but it doesn't really affect the pleasing power of this image :-) kostas
