Would I look completely different if I got a rhinoplasty? (photos)

I think that the goals of facial plastic surgery should be to enhance the individual’s features that are naturally beautiful. This is especially true in rhinoplasty. Rhinoplasty should remove the elements of the nose that are distracting features, such as a bulbous tip, a dorsal hump, or asymmetry and allow the nose to blend into the background. This allows the more beautiful features of the face, such as the eyes and the smile, to better show and allows others to better focus on those things that naturally make you beautiful.For examples, check out the examples on my RealSelf page or visit the link below.

I made a couple of computer morphs of your nose, and animations of the morphs, to show the changes that are possible for your nose in truly expert hands.In the morphs, I narrowed and elevated your tip, and lowered the bump. These are very reasonable changes to have as a goal for a rhinoplasty.I understand your concern about still looking like the same person. There are a few ways of thinking about this issue. The nose is really only a small part of what you look like. Sure, it's an important part, but changing the nose wouldn't change your eyes, or your facial shape, or your lips or teeth or jawline or the length of your neck or your shoulders or how you hold yourself --- it's just your nose. Then, if you want really just a tiny, tiny change, so nobody knows that anything was done, then your nose would still look too long and too wide and too bumpy after surgery, and why did we do the operation?Finally, if the results look normal and natural, no additional attention is drawn to the nose, and that helps you still look like yourself. In fact, if some large-ish features are removed from the nose, then the nose draws less attention, and it helps you still look like you: more attention is drawn to your eyes and your chin and your hair, things that didn't change at all.
You should understand that the changes I demonstrated in the morph require advanced techniques, techniques that most plastic surgeons cannot handle.  Be sure to read the section in the "Learn more" link on how to stay out of trouble while searching for a rhinoplasty surgeon. You should only have surgery if you are able to make yourself very confident in your surgeon's skills. Read that page very carefully. Most plastic surgeons are quite poor at this operation, and I believe my advice will go a long way toward keeping you safe.
I'd love to hear what you think of the morphs. Did they seem to address your main concerns? Should I change some of the features?
Your nose is also a good example of why computer imaging is mandatory in rhinoplasty. You need to know exactly what the surgeon is planning to accomplish -- what features he thinks he can change, and by how much he thinks he can change them. When you see his goals, you'll know whether he has an eye for an attractive nose, and whether he shares your opinion of what constitutes an attractive nose. You'll also know whether the changes he proposes are enough to be meaningful to you, and whether he understands your wishes enough to address all of your priorities. But remember, you're not hiring him for his skills with the computer. The doctor must then show you his before and after photos to prove that he can actually accomplish what he draws on the computer.
In your case in particular, you need to find a surgeon who understands all of the issues I mentioned, and how they fit together, and who can actually accomplish them in surgery. 

Typically, a well performed rhinoplasty will look completely natural after surgery. An experienced rhinoplasty surgeon should be able to decrease the hump and refine the tip in a way that you will see a great result, but everyone else will not even know you had surgery. When you go in for consultation, make sure you see a lot of photos, and determine if he/she performs a lot of rhinoplasty.
