Start with darks?
Man, I'm honestly afraid to start inking this.
I intend to do contoured cross-hatching. The bottom-right half I is to be predominantly dark with deep shadow, and the top-left predominantly light, as if it were a volume of mist illuminated by the setting sun in the valley to the right.
I'm doing test drawings. The second image is pretty close to how I think I'll do the inversion clouds below the cliff edge.
What do you recommend for the first marks? Should I:
A. Start with contour shading?
B. Start with general directional mid-tone hatching?
C. Start with the darkest darks?
D. Outlining?
E. Something else?
I'd like to ensure I create tonal edges, so I'm hesitant to start with outlines, even though that's the most comfortable. What would you do?
How do you like to start inking a drawing?
