Aside from my nose, what needs to be changed for my face to be balanced, youthful, and healthy looking? (photos)

I will agree that proceeding with the nose surgery is a good option, and to feminize the nose, I would consider shortening the nose, decreasing the flaring of the nostrils and raising the tip-up. Furthermore, you can benefit from the Fat Injections to the face, especially in the area of temples and zygomatic bones, in order to achieve a more oval shape of the face. I believe your lower face appears to be very square, especially the angle of the jawline. For this reason, I would consider perhaps either botox to the masseter or bone reshaping as a more permanent solution. As the last suggestion, you might benefit from would be considering the Submental Liposuction procedure.
