Yo NASTY I LIKE YOU.
Ok this is how its done, but I’m not sure if its helping because drawing is more about feeling to me than real anatomy. Whatever I want to draw I just observe it more and remember the detail then draw it out as I fixed the drawing in the process.
1. Sketch the basic, the pose. You can try to draw with dot (many wip online can help) for me I just go straight to this
2. Sketch the full pose with pencil, dont press too hard or when you erase it gonna be a real pain in the ass
3. Add small detail with pencil, just put it there so you have better vision of what to come. For the shoulder and the hip, you can put the bow line like that to draw the muscle and the butt better. I know its hard to understand huhu i dont know any other way to put it
4. Draw it with 0.2 mm pen, I used Marvy pen since acient time (kidding, since I came back to comic)
5. Add details for the muscle, in the thigh, the arm, the back, and the butt lololol
6. Erase all pencil lines, but dont press it you have to be as light as feather or the paper might be crushed. Then voila!
You also need to remember that Zen should be more lean and muscular than Saeran so the line for drawing him should be more thick and firm, while for Saeran case the butt just look juicy
(yummm) I know I suck as a mentor. Please look for more detailed WIP online huhu
