Cute girl. Flattering treatment. No doubt this photograph will become all the more precious with the passage of the years. You have a winner here.

Let me please suggest you use the Color Balance tool to reduce the pronounced magenta coloration of her skin tone.

You may also try a black-and-white rendition of this photograph.

Okay, I downloaded and tweaked this headshot. I adjusted the skin tone in Photoshop using Color Balance and the Hue/Saturation adjustment layer for desaturating the red color. B&W seems to do this image more justice than does color.

I used the Gradient Adjustment tool and selected Selenium 1 for the B&W treatment. And I cropped the image slightly while also applying a vignette to make the headshot stand out. I removed a whitish spot (a distraction) on her right shoulder.

Note that the Selenium 1 filter reduces highlights and brings out some tonality in the skin tone.

This way, the image takes on a classic presentation.
