Simply amazing
This is some of the best flash work I have ever seen. If you did this by hand, then my jaw will officially drop to the ground. Loved the laser-scroll text. Just one con was that the scene with tails in the plane wasn't as high-quality (after hitting replay, I'm adding this: there's no shading, that's probably why), probably because of the difficulty of the 3-d rotating shot, but the fact that you pulled it off without any major losses in quality just added to it. Now some corrections for past reviewers/notes for people seeing this for the first time:
The song IS Ichirin no Hana, Huge Hollow Mix by High and Mighty Color, and yes the acutal song sounds exactly like it does in this flash, there are no glitches in the sound quality. Also, yes it is the intro song from the anime Bleach.
The greyscale part looks much lower quality than the rest because it is clips from Jeff Yandura's much earlier prequel, "Sonic X: Chaotic Battle."
