|Interestingly, I find the contrast to be too high. (yup) The boa shadows are too dark, or way too white - loss of major detail here.
The problem appears to be the placement and intensity of the rear light, causing blowouts on the left and not enough dynamic range in the front.
Yes, your wife's eye liner is way too thick in this, giving her hollow eyes (post processing?)
Most if not all of the image could have benefited from a single additional over the head ( toward front ) light that allowed you to properly expose the face while not having to blow out that left side area.
Overall, tho, lighting aside - very nice image, composure, model and pose.
