Ask professional photographers to answer perspective questions about photography? The main problem is that the nose is big and wide.

I don't know what machine you are using. The solution to the big nose problem, 1, leaves a distance of at least 2.5M; 2. Try to shoot with a long focal length to completely solve the problem of a big nose. As for the problem of yellowing indoors, I think it may be that there is something wrong with your white balance setting (it is estimated that the place where you filmed is illuminated by incandescent lamps). As for "Star White", it is definitely a late PS, and it is impossible to have such an effect on the spot. I hope it helps you.
