Pretty good. It been quite a couple decades since I last heard this song and played the game. From what I remember of the video on the CD, you did a pretty good job in keeping time with the original. I do understand nconde25's concern with some of the images remaining stationary for a bit. I don't necessarily know if he is familiar with original video, but Sonic is stationary in those scenes and just standing there looking at Doctor Robonik's metal sphere before executing his spinning attack.
Nice work!
