>>5251330If it were me, I'd start off separating my studies. Cross-hatching can be used to denote value, but its a separate skill on its own that shows planar information in a certain way.
When I tried to incorporate hatching into my master study of Jean Baptiste Greuze, I'd find myself using too many line to indicate cross contours and it effected the way the values were set up.
Reduce your values to 5: center light, half tones, shadow, core shadow and cast shadow- and you should be able to get most of the most out of the study without too much confusion.
