Unless this involves mantis shrimp, I dunno man...
Dubstep + deep sea animals just isn't really working for me I'm afraid. I might be able to see it, but I just don't know.
My beef is with the repetition. I don't know if I said this to you before, but the foundation of a good arp/ostinato is that it evolves and changes over time, even slightly. One time in four has an anticipation of half a beat or something silly like that can make a big difference. When I write a snare cadence (pattern) for a piece, I have it go ABAC with each letter being a measure and representing a variation. Then that gets varied over a greater scheme. The same can be applied here.
Also, you can have a distinct and unique B section in another key or with a new key structure. That little arp would go away and something new would come in.
Perhaps the biggest thing I have about this track is that Antarctica II is a journey. As you scroll down the image, it evolves, it changes, it becomes wholly new things with each new layer of the ocean with new creatures. I really wanted to see that in your piece, but I just didn't get that vibe at all man, and it's MAKIN' ME MAAAD. D:<
Anyway... the mixing and mastering is pretty good. I might tone down the high wah-wah thing a little bit or pan it or do something so it isn't in my face the whole time. As I know nothing about dubstep bassery, I shall take it that the bass was good as everyone else seemed to think so.
Keep it dubby buddy,
