Hello everyone.
I decided to ask here as a last resort because this has been extremely frustrating for me these past few days.
There’s a small shadow under the ear and no matter where I move the lamps, or change their Energies, it won’t go away.

I’ve attached the .blend file in hopes that anyone can take a look at it and give me some advice.

I’d like to keep the amount of white areas (bottom part of the ear and down-left of the left eye) at a minimum, but this shadow has been getting in the way.
Any help is appreciated.
