I'm really liking this stuff but there are 2 things I would address-

1) Levels: The bleepy line that goes through the track is a possibly a little low.

2) Variation: The bleepy synth line is a bit too static and would really benifit from some extra programming to keep it more alive:

I'm thinking taking the loop, cutting it in 1/2 (removing the last note) and repeating the first half to create a variation then pasting this infront of a copy of the original loop.

It's a good trick and you can repeat the process with smaller and smaller cut and pastes till you get down to just the first note rattling!
