Not bad
Animation, what little there actually was, looked a bit stilted and stiff. It sort of made it feel a bit more authentic than it otherwise would, as it was a practice in early Japanese animation to actually animate as little as possible, something that you've captured perfectly here. However, whereas they masked their minimal use of animation pretty well, it seemed here as if you cut corners, hoping to rely on the near-authenticity of your artwork to carry you through.
As for your artwork, it was sound. It definitely created a convincing atmosphere, though I couldn't tell whether or not you'd painted the backgrounds yourself, or nicked them from the show. The disparity between them and the rest of the artwork was pretty jarring. That's not to say that the work as a whole wasn't competant. That's not the case at all. It is, however, to say that in comparison to the backgrounds, the rest of the art has a noticeably lower quality, which could serve to keep viewers from being completely immersed into the flash.
Even so, I'm loath to dock someone points just because the clarity of the backgrounds doesn't jive with the rest of the flash. More to the point, regardless of whether or not you nicked the backgrounds, the entire presentation came together rather well, from the fonts used in the text, to the character portriats that presented the dialogue. And as it's a visually appealing piece just the same, your flash is accomplished in this area.
The sound was spot-on. There's little to complain about regarding this particular aspect of your flash. Some may consider it a shame that you didn't include voice-overs, but I'm of the mind that unless you can find some talented voice actors to help you along, you're better off not bastardising the material you're paying tribute to, by getting some douche with smoker's lung to come out of his mother's basement and do a horrible parody of some of anime's most beloved characters.
The story was alright. Not bad at all. However, your flash was brought down a few notches in this area by the dialogue, which while being true enough to the source, ultimately felt forced.
It seemed as if you ran into the same problem alot of fan-fic writers do when it comes to putting their own words into the mouths of someone else's characters. It all sort of reads like something each character would say, but ultimately isn't all that compelling.
I felt that there were only the most cursory of differences between each character's personalities made evident through the dialogue, and while I wouldn't strike points off for a lack of voice over, it is up to your dialogue to pick up the slack left in the absense of voice work. It didn't completely fail, but it does need work in order to draw the viewer in.
All-in-all, it's a decent work. It's technically sound, and features a subject matter that us geeks from way back can behind. I can see this getting good scores all across the board. Thing is though, that as far as I'm concerned, this thing needs a bit of work before it meets its potential.
Oh, and just to save you the trouble; Flash by Cyberxion: 0. And why is that? Because I'm too stupid to figure out the programs, despite the numerous tutorials out there. Even so, I know what I like, and this was merely passable. Good luck in your future flash endevours.
