Check my Machinima Out.
I just have two things to say:
1. This is a must, and pretty obvious for anyone who makes Machinima. If you're going to make Machinima, you absolutely need a capture card. Talk to Ian, Stab, and Asaic about which one to get if you're serious about it.
2. I didn't really think there was a plot in this. It seemed like you just went around killing people and then added in youtube speak later. I would go back and rethink your plot a little bit, because I don't see one right now.
What I think would be an excellent idea for an AC2 machinima is Altaïr waking up in the Renaissance and having no idea what the hell is going on. I think that could have a lot of potential. Talk to James when he's on here about Machinima, as he's avid about making it for Assassins Creed.
You can also look for digital ph33r's videos on youtube about how to make machinima. Just search them on youtube, I think they're in a six part series.
One more little piece of advice that needs saying -
Turn your HUD off. It's distracting and having it on looks amateurish.
