Hey man, you've got some good content, and I've got a couple of comments...
First off, your 3d stuff is the strongest thing on your reel at this point. I'd start off with either the car or the room with the fishtank. Those are the two best things you have on here. Your roto stuff is good, but there are some drifts and flickers in there that you might want to fix/polish up a bit. And the one with the girl and shaky camera appears to be good, but it's hard to tell, because you put the matted footage over a black background. Maybe if you put in a different background than the original, to show how the edges look after you roto'ed them it would help.
And just my opinion, the content doesn't really fit the music. I'd try picking something a bit more upbeat, this stuff is a little slow. But if you like it, keep it man.
You've got some good stuff there man, a little polishing here and there, and you'll have an excellent reel!
