What kind of rhinoplasty should I get for my nose? I would prefer no implants

Based on your photos, a combination of subtle changes to your tip, columella, dorsum and middle vault will create a significant, nice change to the appearance of your nose overall.  Although it's difficult to give definitive recommendations without the aid of an in-person exam and morphing your pictures together with you, you would likely be able to achieve a look similar to Jamie Chung's with an open rhinoplasty and septoplasty with osteotomies and possible ear cartilage harvest.  A spectrum of changes can be made to the appearance of your nose using grafts from your own body - from mild to dramatic.  The changes that will look balanced and attractive on your face is something that you should make sure your surgeon understands, and is also able to technically achieve.  

When looking at your pictures, you are a beautiful women.  The goal of a rhinoplasty in your case would be to make some subtle changes that would enhance your natural nose.  In your case, creating more definition and narrowing of the tip would be beautiful.To create more definition in an Asian nose, you have to take the thickness of the skin into consideration.  The skin on an Asian nose is typically thick.  To create more defitiion in a thick skin nose, a rhinoplasty surgeon must "push out" the skin to make it appear more narrow.  This is similar to a tent.  If you push out the top of the tent, it will appear more narrow.In your case, I would suggest pushing out your tip with cartilage grafting.  The cartilage could be harvest for the nasal septum.  The type of graft I typically use in this situation is a shield graft.  Depending on your nasal anatomy, there will be other techniques that I would use.To narrow the base of your nose, I would suggest a alar base reduction.  If you wanted to narrow the top aspect of your nose, you could consider breaking the nasal bones to make them more narrow.I hope this helps.  

Asian rhinoplasties, like other "ethnic groups" , should minimize subtle differences if that is the patient's wish and allow them to maintain certain ethnic traits if that is also the patient's wish. In your case, a well defined tip can be obtained with  cartilage manipulation and suturing. Osteotomies are done to narrow the width a bit and the ala (openings) can also be narrowed at the same operation. I cannot comment on your dorsum (profile) b/c you did not show it in any of your photos. However, I believe that this operation is common and your objectives are reasonable.
