After reading your post about whether to keep going on a painting, I decided to keep working on this one. Charcoal feels easier to control, but I’m learning how brushwork changes with different surfaces—I’ve read Kevin MacPherson mentioned how gesso board and canvas respond differently. I use acrylic gesso-primed sketchbook paper for practice, and while I was ready to call this finished, giving it a day or two made me want to keep going.
