The irregularity in her nose makes it look too short in the before picture.  By building up the nose, it appears to have a more substantial length, even though I didn't change the position of the tip.  This is an interesting illusion relating the apparent length of the nose to the height of the dorsum: the higher the dorsum sits, the longer the nose appears to be.

Similarly, if a patient has a long nose that I can't get quite as short as I would like, carving down the dorsum a teeny bit more can make the nose look a teeny bit shorter.
