For boots and outfit area, I'm not sure it really adds something.
I'm kind of "against" the over-use of ultimate-only-CVS-type-line-delimitation for shading. (sorry for the weird sentence)
CVS type graphics also have "flat" 1 color areas, not only delimited colors with one line. (you did it well in hair area.)
just check Vice.
There is plenty of these exemples in all CVS characters.
As an exemple, just check how Hades's work has progressed in time.
@Chucho : Hopes it will give you motivation to make Lili!
