Cute toon! In some parts the animation felt a bit off, it didn't feel weighty enough when some characters walked. The main lamb in particular seemed to levitate while her feet barely touched the ground, and this could be fixed by having her head bob up and down a bit more. Also, the backgrounds in some areas looked sparse, the forest looking noticeably barren because there were no trees in the distance. It felt more like a park in the evening rather than a dense, ominous forest, which I think is what you were going for. I'd recommend drawing some scenery without characters just for practice sake. I could sorta guess the twist based on the title, and how obviously scary the wolf was made out to be. Despite that though, the ending was really sweet and tied the whole cartoon together. Plus, I have to commend you for doing frame-by-frame animation in an era of tweening and puppetry. Good stuff!
