Such a waste of what seems to be talent...
It looks like you have the talent to make some really great stuff. This just wasn't it. I liked the background and how you had the rays of sun and the cloud floating by. It was nice. The mule wasn't that bad but it could have used work. I think you just need to take a little more time in making it and you could pop out some great stuff. Maybe work on sounds a little too because the sound kept cutting out and then coming back for what seemed like no apparent reason. Stick with it and get a better movie idea together.
