The Beast with One Back and a Buncha Heads

So I was out walking near Pasadena the other day and it started snowing. I was in a nice place to hike and I had my coat with me so I figured I'd just keep on walking. I was making my way down this steep hill and I must've hit a patch of ice or something and I slipped and started rolling through the bushes and sticks and rabbit turds. When I stopped I got up and realized I was in a clearing with a bunch of dead trees. Then I heard a scream. Not just any scream, but a blood-roiling cry of rage! I turned and saw some dude in armor swinging two swords hopping around on a giant hundred foot long snake monster with five heads and nasty sharp pointy teeth! Luckily I had my camera with me, so I snapped off a couple of shots and got one that made really good photo reference for this next painting:
