5 year old Locke meets Alpert, draws smoke monster?

Here we see John Locke when he is five years old. He is living in a foster home with his foster mother Florence, his foster sister Melissa and a foster brother (this is all we see, there could be more people/children living with them). We see John playing backgammon (a game he played with Walt in season 1) before Melissa knocks the pieces off of the board.

Richard Alpert shows up again to see if John is suited for his school for gifted children. He notices a drawing that John did and seems intrigued by it. It seems like it could be a drawing of the smoke monster with a person, much like what happened to Locke in season 1 ("Exodus" part 2) when the monster tried to drag him down a hole (there's the original shot and an enhanced shot below). If it is the smoke monster, how is John drawing it at age five?
