The guy with the hamburger is trying to enter the person with
the crescent moon. They're kneeling down instead of standing or
sitting down which would have been easier to draw, this could mean
they trust each other as friends or best friends but not closer.
The crescent guy is opening up to the hamburger guy, but not
forcing him to do it. The hamburger could represent a male mind,
the crescent a female, or maybe the moon being bigger, a
representive of someone with a higher social standing compared to
the hamburger. This could mean that the crescent is missing
something, so the burger is trying to fill it up. I would say the
crescent is hungry and the burger is trying to feed the crescent,
or trying to fill up an emptiness, meaning the burger who is in a
better state of mind, is consoling the crescent. Or it's just
someone's lousy effort in being artistic
