Yes, your nose can be improved-
I class noses such as yours as "minimal Rhinoplasties".
It might even be able to do it with a Closed (through-the-nostrils) Rhinoplasty.
You have a nice nose - it is feminine - do nothing is a perfectly reasonable, extremely cheap, and very safe option !
Since I doubt you will take that advice, I will give you more.
It is nearly as much surgical work to do a minimal Rhinoplasty as to do a lot - and nearly as many things can go wrong.
However, a full Rhinoplasty can be done under Local anesthesia and sedation - I just don't recommend it.
