I like the rhythmic drive. The change at 0:14 is nice, the way the opening builds up. I can hear that each individual part is quite complex - this makes it interesting to listen to. 0:20 didn't feel quite right to me. I'm not sure what it is, but it seemed to lose the pulse (strange when everything is so rhythmic).
At about 1:17, I think the bass instruments (are they low strings?) could be mixed a bit louder. They seem to have an interesting part.
I think this whole thing could do with brass or synth brass to help punch out the melodic accents. At points, it felt like the strings were a bit weak.
