I like the dark, wavering synth bass at the beginning, although the panning there is a bit strong for my tastes. The beat is really coming together nicely by :30 or so, and the eerie "screeches" at :35 help add some flavor. The texture is still pretty minimal, though, with not a lot of mid-range frequencies. There are a lot of cool individual riffs here, like the ominous synth riser at 1:32, and I'm digging the prominent hi-hats there too. The "Ireland" vocal line is a bit overused after a while, and overall the piece doesn't have a very strong sense of progression. There's some variation in the synth patterns, bass, and beat over time, but I'm not sure it's leading anywhere in particular.
In the future, I'd challenge you to structure your piece around a couple of climactic "events" - it could be a particular melody, or an atmospheric bridge, or a notable change in the sound design, etc. Any stand-alone piece (i.e., not part of a video game soundtrack or playing in the background at the mall) should feel like it's telling a story, and this piece isn't quite doing that for me right now.
That said, I really like the instrumentation and the creative drum patterns in this piece. The production quality is also solid - the frequencies are well-balanced and come through the mix clearly. I also appreciate the neat compositional details, like the white noise/filtering effect at 5:50. The transitions are all very smooth, and the breakdown at 6:05 before you slowly brought back the beat for a "last hurrah" was a good idea. As I alluded to earlier, the somewhat aimless structuring and minimal texture are my main complaints here.
Keep at it, C-Lehman! ^_^
