The best...ever...
The bar for flash gets raised again and again, and as far as I can see, and I see lots of flash movies all over the place, this is probably one of the top two or three best animated flash movies as of right now. Although some other movies might have some technical stuff that may be better, I personally have to say this is the best I've seen, and the story/idea is the kind of stuff I like to see.
First off, the backgrounds are extremely detailed, the character design/animation is smooth and professional, and the ambience/ timing/ lighting/ camera movements/ special effects are spectacular. And of course, to top it all off on the visual side, you got the great 3D animation. The sound effects are very well executed and the sequence at the beginning with the song sets you up for the rest of the movie. The contrast between the calm and the action is well played out. So, basically, point by point, this Flash has everything modern Flash has to offer.
If you made the entire series (at least 30-40 minutes of actual animation) and put it all on a DVD with special features and stuff, I can almost guarantee you that at least 1,000+ people would buy it. Even other merchandise, like posters or t-shirts would probably sell. If you advertised it at the end of your final episode on NG, you would make a lot of money, dude.
