Wow. That reel was incredible.
I will say two things, one positive, one negative.
The positive thing is: I think the music should stay. Why? --Because you did an EXCELLENT job of making it work with your imagery. Many people hate the generic techno soundtrack simply because many demo reels incorporate it without actually bothering to sync it to the images in any meaningful way. But your reel shows real attention to the way the two work together. When the mood of the music changes, the images change appropriately. When the music scratches and breaks, the image warps and bursts into static. It's a very, very nice piece of editing and I think you should keep it that way.
On the other hand... quite simply, I think you should lose the talking burrito. It isn't anywhere near the quality of the other stuff on your reel. On top of that, the fact that it talks is lost because you don't have the audio dialogue as part of the reel. So I'd say ditch it completely and either put in something else or shorten the reel.
Fantastic work, thanks for sharing.
