What I do as a first step with any image I comment on is copy it and open it in Levels to evaluate the tonal range. In the first image a few highlights are clipping as they should be in a full range image but there's an absence of any rich black tones. That may be intentional on your part and in any case it's a subjective decision, but for comparison purposes here is an edit with deeper blacks (shadow slider moved right) and a bit more contrast in the midtones (middle slider moved right). There is also some selective USM on just the front of the face, similar to how I'd apply it on a photo of a real person:
Here since the overall field of the photograph is light I used a 255, 255, 255 mat and 0,0,0 rule which "anchors" perception of the tonal range in the photo.
