Wow really sweet!
I love the way you made all those animals approach the guy playing the guitar. Very smooth and each had it's unique style. Also a very nice message at the end. Lot of people will come to you for friendship when your life is going well and in tune but the one who remains even after they are gone is the true friend there in your time of need. Great selection of music also.
Overall it was really good even something I could share with my friends. I think you just need to improve your art slightly and make it as good as your storytelling and animation. Good luck on your future submissions and looking forward to seeing more from you :)
