Opened in CS3.
Tonal Contrast Nik Efex. This is a feature that almost takes over the role of sharpening. You can selectively control the highlight, midtone, and shadow contrast, so it makes details pop.
Cropped and resized.
I did not like the background colors and had in a previous edit done a layer mask and changed the color of the foliage. That didn't work out too well and looked sloppy.
So for this edit I decided to go with BW. I converted in Silver Efex, pumping up structure and contrast.
Lightened the face and eye with Viveza, which is a selective editing tool.
Then I added some glow with Virtual Photographer BW Diffuse filter. Virtual Photographer is freeware. It's great to have if you don't already.
Finally I added a slight vignette with lens distortion.
