Personally I think the right side looks much more natural but as Doopliss mentioned, the portrait lighting isn't the best example.
Here is an image I made for some feedback about a lip issue with the face I use.
The whites of the eyes look plenty white to me even though all these images are in shadow. They're a little extra shadowed on the upper part of the eye but that makes sense given that there's an upper eyelid and a brow hanging over them. That is how I would expect light to work and it adds depth. Everyone is entitled to their opinion but I'm really not seeing how these eyes could be considered dead, soulless, grey, "black holes," etc.
But again, I'm not trying to argue about it or review the eyes of every player in the game. Everyone should leave whatever feedback they feel is appropriate.
