Hi, I've been drawing for a few years, but I feel like recently I've stopped improving. I usually draw in pencil with a mix of drawing from photos, from imagination, and, when I can, drawing from life (usually my own hand or objects around me). I'm not sure how exactly to push myself next to keep improving, I started drawing only with pen but aside from figuring out how to crosshatch it doesn't feel very outside of my comfort zone. Does anyone have suggestions? It would be very appreciated, thank you.
