Could I have a nose job to make my nose smaller or less pointy? (Photo)

Yes, your nose could certainly be made "shorter" and less pointy looking.  I think you have realistic concerns based on your photos.  Find a good facial plastic surgeon in your area and set up a consultation!

Set up a consultation with a surgeon who can provide you a realistic impression of what can be done based upon your anatomy. Yes, a nose can be shortened and a tip made less pointy. The extent of which this is possible for you is based upon your anatomy. Best wishes on  your journey.

You can have a more refined nose that is
natural in appearance with a rhinoplasty to deproject the tip and reduce the pointy nature. I perform these surgeries with closed technique
to preserve the structure of the nose and minimize visible scarring.Kenneth Hughes, MDLos Angeles, CA

Rhinoplasty for the overprojected nose etc. can give you what you wamt with a natural looking nose IF u see an experienced rhinoplasty surgeon who does natural looking noses. 

hugojellybean, interesting name there; yes to both of your questions by the way. Seek the opinion of several facial plastic specialists with over 10 years of experience. Look at their web sites and make sure they have photos of patients similar to you. I have over 200 photos on my site. Do your homework before you visit and see more than one surgeon. Good luck!
