If you want to bring that dappled sunlight to the next level, try boosting the saturation of the material at light --> shadow hard transitions, on the shadow side.
Typically, the light going through skin shifts to a bright saturated orange/red when strong light is applied (subsurface scattering effect). How much or how little you want to push it is up to you, but I could definitely see the spot around her cheek, nose, mouth and hair benefitting from this pop of color.
