[This is my first puzzle where I actually attempted my own illustrations, (beyond straight lines and letters). My soccer-loving son has not stopped mocking the soccer drawing, ("Have you ever seen a soccer goal?", "That player is not kicking", etc). My defenses are that: 1. I have never claimed to be able to draw anything, 2. I actually drew these while on a bumpy train ride commuting to work, and 3. I actually really like my drawing of Cookie Monster!]
