Wow might be one of the most moving animations I've seen in a long time
Considering this was in memory of one of your best friends I can only imagine what you went through. And if he were to see this animation he would be proud of you. That being said the animationw as superb. If you ever get the chance you should submit this at a film festival or something like that it's an A+ winner in my book.
Keep up the good work and make your friend proud!
