Quote - winvdb - that looks really good, the face shape is great. Unfortuntely the lighting on the skin does not match the lighting on the hair (getting decent looking hair that matches your render is hard!) and this really detracts from the realism.  Also the eyes dont look quite right.

I am curious here. The eyes, yes maybe the cornea blocks the light a bit too much.

The hair I would like to understand. I am using an IBL image as light source which has multiple light sources. The main light source comes from one direction and lits the skin and hair equally. What specifically make you say that they don't match? Not wanting to argue, but wanting to understand what should be different

I did not mention this earlier, but it is an octane render, so the lighting is different as in firefly. This to avoid misunderstanding
