i did a bit of photoshop doodling with the nose profile..
although the camera angle in the photo makes it a bit tricksy it can reveal a tidbit of info..
the red stroke is the outline from the photo. As you can see the bottom of her nose is a bit more flat wich in turn makes her nose more pointy like..
i think if you move the point(s) marked in green (only the points on the tip of the nose) a bit down near the spot marked in blue, you'll get the right shape...
it isnt much movement to make that little change so be careful
and now stop fixing errors that isnt there! move on to texturing or give her that needed hair do
Looking forward to see more
