Is my nose too large for my face or my lips too small? Or are they proportional? (photos)

Thanks for sending in your question and photo.  You are an attractive women and certainly don't need any procedure.  You could consider rhinoplasty which could include nasal tip refinement, dorsal reduction and nasal narrowing and possibly lip enhancement. 

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 cephalic rotation of your tip to turn
up your tip slightly 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.

Hello Ana.   I think    first  , you need a personal consultation  to evaluate  your case. Tell you about  your options. Each case is very different.RegardsDr  Hernandez Pizzoglio

Ana, 
Thank you for the questions and the pictures, but the single shot you provided is not enough to do a "facial analysis." A full profile picture and straight ahead picture are the minimum necessary. As you know, angles matter in pictures so we are only seeing a small slice of the pie, so to speak.
