What the title says. Also don't make the doodles too complex. Note: The doodles can't have color and it needs the same brush size. If you pick another brush size than 10, tell me which brush size you used so the outline is equal. Also, the doodles have to be diferent. You can't make a doodle, duplicate it and modify it. They have to be unique.
