Can i shave my nasal bone, nose tip, radix and make my nostrils smaller? (Photos)

If you are dissatisfied with your nasal profile appearance, rhinoplasty surgery may be considered for lowering your dorsal hump, and repairing your hanging columella, for a less distracting nasal appearance. I hope this helps. Sincerely, Dr Joseph

Things may seem easy for the lay eye, not in your case; please note down:
-you suffer the so called (I don't like the term) parenthesis tip deformiy, in Europe we name this overly vertical or verticalized lateral cruras of the alar cartilages; this leads to boxy tip shape, poor alar suppor, nostril retraction/rim raise and a poorly defined tip; you do not suffer from overly large nostril, just happens your too vertical cartilages fail to push down the nostril rim to its correct position and this makes it look falsely oversized
-you also have a short caudal septum
-and the mentioned by you dorsal hump

You need a surgeon with experience in structure rhinoplasties with modern and adavanced maneuvers mastering, to relocate the alar cartilages, reinforce them, marginal grafting (aka articulated), tip grafting, septal lengthening, etc.

If a basic classical rhinoplasty is done in such anatomically suboptimal nasal skeletons, the outcome is calamitous, revision guaranteed.
