it looks o.k. to me. perhaps with more realistic lighting, e.g. hdri, and doing something to fix it so the hair doesn't have those white areas showing thru. try changing the set-up from a 90s-style reflection map for the eyes to lighting and an environment which is reflected by the eyes. it takes several chapters of a manual to explain how to do that, unfortunately. they were telling us to use reflection maps back in P3, in order to fake what real 3D renderers could do by default. time to move into 21st-century methods. P7 is capable of doing it, even if the renderer is the slowest of any known renderer, other than maxwell IMVHO.
