Woah, this is one of the best submissions I've seen in awhile. I think the lizard is supposed to be female while the bird is male. The animation was really good in this. I can tell that's Johnny Cash singing. It's weird, because I thought I knew a lot about him to know all his popular songs. I couldn't help but think Tlaloc might be backwards for something.
It is not. It's just great to see this wonderful environment you have created. There's so much going on and so much detail. I think my favorite thing might be the clouds that show up at the end. You really have no idea what the outcome is going to be.
