1) Paint the eyes white as normal. Do not dot the pupil.
2) Apply very watered down Ice Blue. This will take a few coats, and cover each layer less and less area each time (so you have less on the cheek and more around the eye socket) Note how you can still just about see the eye through the blue. Make sure you don't go above they eye socket too much as it won't look natural. You know, because glowing eyes are natural.
3) Re-apply the skull white to the eye. Sorted Psi-eyes!
Psy-eyes with lid on -
(perhaps a bit too pronounced on the upper part? Doesn't look natural. It is important to make sure you only paint where the light would go. Heavy handed ftw!!)
Daemon Prince Eyes/Glowing runes -
Bionic Eyes -
Black Legion Marine Eyes -
Basically, experiment, yo! I am not the best painter in the world by any stretch but I work with the tools I have and this looks kind of cool, especially from table top distances. Hope it's helpful to you guys and gals
