I had 4 premolar extractions which I am trying my hardest not to regret. Can I get professional opinions? (Photos)

I went into this journey ignorant and unaware of my options. I would love to get some professional insight. My current orthodontist said that it was necessary for extractions because of my overbite. I would lose my teeth because of their positioning. I been thinking about a reversal and getting implants. I feel that my smile is shrunk and that it has become too narrow for my plump features.
