I love the music David, but I'm sorry to say the video seems a bit bland to me. Very "white", and the main object (the white tendrilly snaky thing) never really changes much, just keeps spinning around and around, morphing and duplicating and spinning some more, but still seems substantially the same. Maybe this is what you were going for.
The few full screen overlay effects you do use from time to time (the red/blue flashing and the white noise) seem pretty rudimentary/elementary. Also, I'm not a fan of how the sidebars seem to switch randomly from white to black to white. Actually, I'm curious why you have sidebars at all, rather than staying full frame the whole time.
Obviously those Pollygrind Film Festival folks know what they're looking for, since your video was made an Official Selection. I just don't happen to agree with them. Sorry David!
