Advice on strong and unfeminine side profile? (Photo)

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."More feminine" usually means "smaller and less prominent" when it comes to the nose, so in the modification I narrowed your tip, lowered the bump on the bridge, elevated the tip, and then brought the entire nose back closer to your face. I paid special attention to lowering the height of the bridge up where it begins, just below your eyebrows. If that area isn't lowered, then after surgery your profile line would look like it slides from your forehead right onto your nose, without a little dip below the eyebrows, like a Roman statue. That's not a good look.
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 "Web reference" link on how to stay out of trouble while searching for a rhinoplasty surgeon.
I'd love to hear what you think of the morphs. Did they seem to address your main concerns?
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 a beautiful nose, and whether he shares your opinion of what constitutes a beautiful 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. 

Hello and thank you for your question. Based on your
photograph, you may benefit from a tip refining rhinoplasty. Your surgeon can
accomplish this by trimming, suturing, and reshaping the cartilage in your
lower nose. You may also benefit from a nasal tip deprojection and a conservative dorsal hump reduction.  Make sure you specifically look at before and after
pictures of real patients who have had this surgery performed by your surgeon
and not just a computer animation system. The most important
aspect is to find a surgeon you are comfortable with. I recommend that you seek
consultation with a qualified board-certified plastic surgeon who can evaluate
you in person.
Best wishes and good luck.

I agree with the others that your chin and jaw structure is aesthetically ideal.  I do believe that changes to your nose would create a better balance between your nose and existing facial structures.
