I love the absurd humor here. The plot is fun, and I like the characters. I do think it could have moved a little bit faster, but overall pretty good.
My main problems were with the lighting and the camera focus. Often close up shots were out of focus, and the lighting/light balance was sometimes too dark (I also wish the scene was overall darker/creepier when they visit the lamb. This could even have been done in After Effects with a tint and fake candle lighting).
My favorite parts were the lamb songs, and the sets. Keep it up! I'd like to see more with these characters.
