Light control is crucial to an image's success. I'll usually add or subtract light to direct the viewers' eyes to where I want their attention. But there are times when it's not necessary to do much more than record the image. Natural light photographers are married to this technique... whereas I simply befriend it when it's the best method... which isn't very often. I prefer to "play the field".
In today's image there was rather flat light on her, and a bit of top light, but that's just fine. I added light on a few other images, but even at a low power, it didn't match the feeling of the scene.
