How much can my nose be fixed? 6 years after being punched.

Hello, I had an incident about 6 years ago a random guy in the street throw me a punch on the left side of my nose and it got crooked. Unfortunately, they werent able to see my nose crooked at the emergency and the ENT called me a little too late for manual reduction. I have my left side that is concave up to the eye level, a deviated septum (not severe), and a nasal valve collapse in the middle right side of my nose. My question is: how much of improvement can a rhinoplasty bring me? I am not looking for the perfect nose but only a straighter look from the front view, and fix my deviated septum allong with the nasal valve as it difficult for me to breathe from my right side. Also, can a closed rhinoplasty be possible in my case? I have attached 3 photos of me now, and 1 photo of my nose before the incident.
