That was pretty creative!
I really like how you mixed David Firth's music with a style reminiscent of Neil Freebairn's To Kill An Assassin (you should check that out when you get the chance). It's too bad that a lot of people missed out on checking this out, because this is one of the better music videos around. With that said...
In terms of art and animation, it's similar to To Kill An Assassin, but with much more in terms of actual animation. Speaking of which, I like it when people mix tweening and frame-by-frame together, and you did a great job at it. Plus, I liked how you synchronized the animation to David Firth's music. As for that part, you have made a wise choice when it came to Audio Portal music, something different outside of the metal and electronica (which I happen to like I might add). As much as I loved watching Katan, Bitey of Brackenwood, Tankmen: Dual, Serpent's Grave, and Fallen Angel; this is kinda reminiscent of the flash cartoons that were made between 2000-2003 when people on here were doing flash for the hell of it.
What I do like:
-Original, which isn't as important as the final product
-Good song selection
What I don't like:
-The speed of the faces at the preloader was near blinding.
Overall: Here's a nine out of ten for doing something that I found quite enjoyable.
