good setup, I thought myself of making a “Self portrait with painted edgeloops”. Finally I thing I’ll get a plastic head for better manipulation.
The goal would be to make photos with different lightning setups and replicate them in blender, to get the feel of the shapes with the shadows.
As for your model:
Very good overall.
I saw something strange at the top of the eye, like it is too thick. I shows best in the “a better orco texture” image
Also, your eyebrows: look at your front photograph, see the “inside” limit of your eyebrow finishes at the same point of the inside limit of the eye below.
But in your front model the eyebrow goes far more inside.
