A really great exercise is to stretch your memory and draw without looking at the subject. I encourage my students to begin by staring at a subject for 5 minutes, memorizing as much as you can, then draw what you remember. The next exercise is to stare at a subject for 8 minutes and then draw from your memory. Lastly, stare at another subject for 10 minutes, and then draw from memory. Ask yourself: What did I have to do to remember what I saw — did I count things, or try to memorize shapes and angles, or did I visualize each line to store it in my mind? Try this memory exercise over and over again to improve your drawing .
