Tracking someone's face in an interview successfully

Hello There. I would like someone to help me track successfully someone’s area parts of the face while talking in an interview moving their mouth and eyes and head in Mocha Pro 2022 version. I tried the followings settings with some success but not complete success. Especially when it came to the areas round the mouth and the right eye.

If the head turns more than 45 degrees or there are a lot of shadows, it could be a difficult project. When face tracking, there can be tips to avoid the mouth and the eyemovement. For example you could use the X+ button to add occlusion shapes to avoid the eyes and mouth, then regenerate your mesh and retrack.
