This drawing was made by creating a big shape first, as a bounding box, and filling in the details later, and then realizing that the proportions are off. Oh no, why is it still so hard?
Ah well, even though it doesn’t look like the original photo, the sketch is a fun drawing anyway. Instead of a 20-some person, it is now a teenager crashing to the pavement after a daredevil stunt with the BMX bike.
Please, don’t try this at home, kids. Bone tissue heals very slowly and with much pain. Leave it to the pros, who have good health insurance, and are paid to do crazy stunts.
That is all.
