Showing pictures without any kind of additional post processing, contrast boost, or saturation would make it much easier for us to help you with the material settings. Currently we cannot be sure what, in your opinion, is wrong with the skin shader, since we don't really know how it looks straight out of Corona VFB. So if you are doing tests and sharing your thoughts about what could be improved in Corona, it would be best to post the pure images from the VFB without any kind of processing. Or if you really don't want that, you could post both of them - with and without the processing.
The main reason why I think the images you posted are wrong is that if it was an animation, it would be very uncomfortable and tiring to watch. But that's just my opinion, and I could also be wrong - maybe it would work just fine.
