Really liked this, the main hook in particular is quite infectious.
It was floating round my head for a bit after I'd finished listening.

The main thing about it is at the moment it sounds like one of those tracks that is good, but you feel is a slightly wasted oppurtunity, as it could be loads better.
Not from any of the sounds, but as Thomas said, the lack of progression.
After the breakdown I feel that you need to take it up another level, make it more intense.
Possibly even contort the main hook.
It's a short track at the moment, so you've got enough time to build it up a bit more.

The only other thing is the breakdown itself.
It builds up nicely, but it doesn't slam back into the track, which makes it a little bit disappointing.
People need to be able to tell when it's going to kick back in, and at the moment it just kind of starts again without any indication that it's going to do so.

Looking forward to hearing the next incarnation :)
