Eye whites aren’t really all that white. Lots of blood vessels and surface noise. Example below … the bottom one has no tex, and you can see the bumpiness. The plastic material is perfect for refelections.
The other thing is your pose … face on, it’s very difficult to make 3D eyes look real. Try with the master’s face slightly pointing away from the viewer, but with his eyes rotated to look our way. More dynamic, I think. Good luck!
