Not bad at all, I quite enjoy it. Nice storytelling, maybe a bit too conventional for NG.
Your only real problem (but not your fault) is, that there are a lot of Sonic meets Mario spritemovies on this server. Hence, you didn't get that much views or feedback.
Don't let this discourage you, I mean, teejay is watching this, and this guy made world of chaos!!
Just one annotation: It's a bit confusing that Mario speaks with Sonic but he is the only character who didn't get text messages in your movie. You should consider to change that.
