Don’t trace. There’s no hard and fast rule to learning how to draw except this: everything from a face to a fucking space ship can be broken down into simple shapes and gestures.
The only way to learn is through daily practice. Starting from zero, from stick figure gesture drawings and then going up. Get yourself a copy of the VILPPU DRAWING MANUAL. Its an easy google search, you can find it for free and get it as a pdf by typing “vilppu manual pdf” in your search bar.
Print it out, staple the pages, put it in your bathroom along with a sketchbook and a pen (pen drawing is important, you have to live with your fuckups, it keeps a drawing from becoming too precious). Every time you take a shit, copy from the manual for five minutes.
“Disgusting,” you say. “Why would I draw on the toilet?” Because you are at your calmest and your most aware when you are in the bathroom, especially when pinching a loaf.
I digress. Daily practice from a book, with the occasional life drawing session every odd month, along with weekly trips to the arts institution of your choice, is the only real way to learn how to draw.
