Interesting movie so far. I can see a few places in the Special Stages that you can improve. For example, when you go for the first emerald, you take a longer route around a set of bumpers you could easily jump over. It's possible to jump two objects in a special stage at once.
Also, the second special stage, there are the 3*4 sets of blue spheres. There's an area with two of those in a row. Instead of making 2 turns to get the sphere set, you should move forward past the 4 for the first row and grab the 4 for the second set before turning around. Don't understand? Here's a pic.

Edit: *smacks face* ...That last arrow. Move it up a row.
Anyway, now that I'm done watching the movie, I see possible fixes in the Special Stages. Mainly turning a little too late or something like that, but there could possibly be a few things like jumping in the right places. Timing some jumps right, you could probably get Sonic to successfully wade through an entire sea of red spheres unscathed, but that's just a possibiltiy. Might as well try it, right :)
