Is my nose too big for my face or are my lips too small for my nose? How can improve the overall proportions? (photos)

Good Afternoon! I feel like your lips fit your face well. I wouldn't suggest enlarging them any. For the nose, it depends on how your profile looks as well. In order to obtain harmony, we need to evaluate all aspects of the nose from multiple views. By doing so, we can take measurements and morph your photos to see what changes might look like. I would seek consultation with a facial plastic surgeon to learn more. Hope this helps!
