Pretty good, but could be better
Very imaginative, I appreciate the original approach and concepts. But to me it doesn't feel like a dream at all. Instead it feels more like a random fight scene. It seems like the dream setting is more of a cop-out or a way to justify a little bit of randomness. But dreams, I feel, are even more random. I think you could push the dreaminess. Make dreamlike transitions between shots or scenes, instead of logical ones. The concept of time in dreams is often less realistic or straight-forward. Also, there was little to no character development. If it's to be a dream, I ought to know something about the way this monster thinks from the piece. So far... he's afraid of something attacking him, and would love to sail to the stars. But there should be more in his reactions, some level of emotion. I liked in your extras the shot where the beast looks down at the character and there's some level of interaction and thinking. That is character development. There must be some illusion of thought or motive (even if it's a nonsensical reason). Keep at it,
