Um... For own freestyle drawing, usually I end up with cute style (uncontrollable). I didn't do practice for it (the drawing here is already my daily practice😣). Like this post, I started with no draft and the b/w line image above is already the first step..
If... if there is a way to explain why and how, I would like to share too😣 I usually can only answer what to use, like the palette and software. I did live before, but felt too simple and not so helpful as a tutorial, so gave up xDD
