I like most things about the photo, except her hair is completely blocked up. Using the Shadow/Highlight feature in Photoshop it would be easy to bring out some more detail in her hair, but overall, the hair is simply way too dark, given the lighting that's on her face. It seems to me that the original processing or the in-camera settings are a bit too high in contrast,and the saturation level in the hair is a bit too high,causing the blocked values in the lower tones.
Overall though, a nice friendly-looking,pleasant shot of her. Her eyes might be framed a bit low in the composition though. The soft,gentle highlights on her forehead and cheeks are not caused by excessive skin oil, but by the light source being large,and close to her, and by the nature of the light source, which is giving just a hint of specularity...which gives shape and dimensional and depth clues to our eyes. I don't think it's necessary to smooth the skin out, but then again, I prefer "real-looking" portraiture, while many people raised on Photoshop prefer a much more plastic-like skin rendition where people have no pores, no winkles, and look like mannequins. The highlights and her actual skin look "real", but a lot of people want to see women rendered with heavily-retouched,smoothed out skin, a la beauty and cosmetic product ads.
