Interesting that you said you focus on night drawings. This morning, I was thinking about the charcoal pencil drawings and thinking of something I could do in b&w with it that might be a little more involved. What I thought of was a white horse galloping in the moonlight with sort of silvery, long grass underfoot and silvery clouds in a night sky, sort of half-obscuring a full moon. Or something like that. However, I fear I could never pull it off from my imagination. It's too complicated. It sounds like a good idea, but I have enough experience with this kind of thing to be sure I'd be disappointed. Maybe I'll try it. I don't think I've ever tried a night picture. We usually think of horses in sunlight.
It's snowing for real today, and I have loads and loads of laundry to keep me home, so maybe it's a good day to try such a thing. What can happen? I can fail and
throw the picture in the trash. Sure, it might cause some frustration, but maybe I'll learn something from it. I guess I should do what you do and look at pictures on the Internet that show such a moonlit night and see what the colors and shading look like, how clouds look when they're illuminated, etc. Not use the picture to copy, but like you, get an idea of how a thing looks from them.
