My nose appears to be going to one side and people have told me one nostril is bigger than the other. (Photos)

The images you give are partially helpful but incomplete to fully advise you on what is right for you. Exam in the office is best but in general terms, crooked nasal lines can be helped with a rhinoplasty procedure, which may also include correction of a deviated septum in many cases. Nostril asymmetry may require refinement maneuvers with stitches and/or cartilage grafts to the nostril supporting tissues, and/or removal of extra nostril skin in some cases. Set up some consultations with board-certified plastic surgeons and/or ENT facial plastic surgeons for evaluation.

Improving the appearance of
a crooked nose and nostril asymmetry is a common request of many patients
seeking nasal surgery.  The improvements you seek can often be achieved with a rhinoplasty.  I would recommend an in-person
examination so that a surgeon can thoroughly examine the inside and outside of
your nose from different angles, feel the tissues, better understand your
goals, and make more specific recommendations to achieve the natural look your
desire.
