The image is not composite. Like the others, this one was done by applying Sabbatier effect, and then some selective dodging and burning to darken some areas of the background. Outlines, or ridging, are partly the result of Sabbatier effect. They occur in the photo lab as well, when working with B&W Sabbatier photos. Looks like here they were made more prominent by sharpening. Here's the image with selective sharpening in place, it looks a bit better than the first one I posted.
