Select the nose polys and....... stunning!


Here I repeat the same process as before, but now you can see the effect better. SmoothShift > deselect > stretch remaining polys > merge > delete 2-point polys.


A nose tip and...another Saw action...


Here I select a problem area at the base of the nose...
... and slice sufficient geometry to deal with the contours.



SmoothShift a nostril...
.... SpinQuads and tweak.


I also like to use the standard weight map to help control sup-patching. I seldom drift above 40% or below -40%, because the weighting is not edge-based but point based. Red is positive (sharper edges), blue negative.
