I guess I never confessed that: since the beginning, I've used myself, my body, as a reference for drawing, especially since creating LUST.
I realized that this afternoon while working on chapter 4. Drawing the hairy forearm of our hero, I naturally put my left arm on the drawing board to see how my hair flow on the skin. So I took a picture to show you my process, hehe!
I guess lots of creative people do so, it's time I tell you about it, haha!
