@W0LFB3AT5: i preferred to draw eerie scenery, for classes I would often draw what I pictured in my mind while reading h.p. Lovecraft and used Stephen gammell and h.r. giger as references. It was hard coming up with that much to draw for classes.
My favorite is drawing with charcoal, so a lot of shading and different tones.
I took figure drawing classes as well which was a great learning experience, although I remained abysmal at drawing human faces and hands. I personally ought to get better at drawing hands, but I suppose that will be practice over time.
I've been trying to start drawing more often lately, I should try making a few more charcoal drawings again. I mostly use my powers for smut these days, which is fun.
