/ic/ - Artwork/Critique

Working on my own linework this month so I've been trying to analyze and deconstruct favorite doujinshi artist who have art I wanna be able to replicate.
Anyone got pointers on what type of process someone would go through to render something similar to pic related? This doujin, along with a artists like Sakurai Energy and Itou Eight always make my favorite doujins in terms of art.

I'm mostly focused on trying to decipher the technical stuff, like what type of canvas size they were working at to make this, the type of brush, brush size, and the types of strokes they were making to get the lines they placed down; whether they were applying short, slow strokes or long broad strokes. Still have to figure out how these artists decide where to place other elements like hatching, solid blacks, and screentones.
