Hello, I'm not an expert of the subject but what I understood is that the iris don't pop out, it's pop inward. BUT the transparent cornea pop outward. So the light is masked by the right border and highlight the left part. The white dot is the light reflection on the cornea so on the right part. The white of the eyes is also a sphere going outward so the light is at the right and the shadow at the left. Hopes it helps. | Artwod Feedback
