Is It Possible to Reduce the Nostrils on a Big Bulbous Nose??

Yes.  It is called alar base reduction.  This can be performed within the nostrils and the incisions hidden or in the crease between the nose and the cheek. 

Yes, you describe problems that we deal with everyday.  I tend to not like photoshop programs as much as some other doctors and even patients. I think it is more valuable to see before and after pictures of patients with similar features to you to try to get a feel for how the surgeon deals with these problems.  The after pictures are actually results that your surgeon has attained. 

Good luck!

From your photos you do seem to show reasonable goals. Tip skin thickness is the main limiting factor when reducing the size of the nose. An exam would help verify your goals, but certainly refining your bridge and narrowing your nostrils is possible. With refining the tip one must be careful not to overdo it at the expense of hindering your nasal breathing.

You should certainly bring your morphed photos to your consultation as they would be very helpful during the discussion with the surgeon.
