Portrait Perspective and Shading

Hi, Mr. Waichulis. I’m starting on a portrait that I’ve worked endlessly on at other times. The angle of the head is a very difficult one to capture, especially the left eye and the angle of the face by the mouth. I wonder if you could give me some feedback on it. I think I have it this time but before I go on to work on it further, I’d like to be sure. I have tons of them in my sketchbook that didn’t turn out so well. I have included the reference photo.

Thank you,
