One thing I learned in the last few days is that the pupil is not directly on the outside of the eye in a profile shot, since it is beneath the lense, the lense will be on the outside edge and the pupil pushed back a bit, also I see those occlusion shadows on the eye, you can push the values down on those shadows pretty far. They are generally pretty dark. Also the corner of the eye is one of the dark spots on the face . Keep up the good work. These recent studies are looking great
