I think this is especially the case with the nose.
You can at least get feedback in real time with double hands, but it's hard to do that with a nose.
No matter how many pictures I want, the
one I took is a straight line, but
the director who likes straight lines looks pretty, so at that moment, if he thinks straight lines look better, his nose falls closer to straight lines.
If you're curious about the director's taste, you can bring several types of photos you like and ask the director which nose suits you...
and check the reviews as well.
I think this method was quite successful with my eyes... I should have known about this method when I was young.
