A nice drawing exercise to do you your own Gioconda. Follow the numbers. Start in 1. Move to 2 determining the distance intuitively. Then follow the contour down to 3, then to 4. Up to five, then to 6 (remember to try to respect the proportions). Down to 7. Now fly to 1 and down to 8 and finish until 9. Then copy the background starting in the left. If you are left-handed start in 1-8-9-7-6-1-2-3-4-5-1. And then do the background, starting in the right side.
