She doesn't really have a ball on the end of her nose, even if that's the cliché.  The cartilages that form the tip of her nose are wide, and they overlap each other, giving the impression of a ball.

A wide tip will appear to be a bulge on an oblique view of the nose.  If you put your finger on her nose where it begins, next to the inner corner of her left eye, and run your finger down the edge of her nose, your finger will have to bump out to your right as it follows the bulge around the tip of her nose in this view.  In the after picture, with a narrower tip, that bulge is gone, and your finger would trace a straight line from where her nose begins down to the tip.

Now clean off your computer screen.
