Is it difficult to shorten the nose tip (not nose bridge)? Doctors would tell me they couldn’t do it for my nose.

Thanks for the question and photos.  Your nose is slightly over projected, and can be deprojected.  I would not remove any causal septum, as this will overrotate your nose.  I would; however, lower your dorsum slightly to bring it into more harmony with your face.

You can and should have a less projecting tip of your nose in addition to shaving down some of the dorsal areas. Making your tip narrower is also quite possible.
