How much to separate this type of nose?

[distant axle]

Hi!! I've looked almost everywhere on this issue, but most if not all separation guides I've found have models with very tiny dot type anime noses, so I'm at a bit of a loss here. Currently I have the nose separated into Lineart - Highlights - Blush - Shading (as can be seen in the second image), however I'm unsure whether this is the ideal separation for rigging later on. Any tips would be greatly appreciated!!

I would separate the lineart into four layers (each line separate)

that way they can disappear when the head turns sideways

rest of the separation looks great to me
