The problem with the left drawing is mostly proportion and positioning of the features imo.
Especially the ear and left eye which makes the face way too wide, and the eyes being too high up on the face.
I moved things around a bit so that the proportions are closer to what you see in most modern anime and I think it looks a lot better. I barely touched the jaw I only extended it a little bit.
Obviously this is also also a matter of style and taste but some proportions/feature positions do look objectively bad.
