Your surgeon will be in the most educated position to answer this for you definitively. Asymmetries always exist to a certain extent before surgery, and many remain after surgery. Certain asymmetries can be improved during surgery, but in terms of your nostrils the biggest source of asymmetry I can see in your photos is the way the alar base attaches on the right compared to the left. The vertical height of the alar rims is different, and the way it is attached is more oblique on the left vs. right. I would suspect that this is something that was also present prior to surgery, but perhaps not noticed. The short answer would be - if you love every other aspect of your nose, it's probably best to leave the nose alone. If there are other aspects you are looking to change, then it's something that could be discussed.
