Not bad for a quick project. If they're going to be so short I would bump up the animation a bit. The brief ending was comical.
Is this the best you can do?
At the moment yes. I am 14 and I am aiming to improve a huge amount through the years.
pretty smoooth looking work. short and sweet too.
Pretty funny but the animation could be improved. You should do storyboards or rough animation then zoom in twice and trace the final frames on another layer. It takes longer, but it looks a lot nicer.
