Make a longer version
The title pretty much sums up my only beef with this audio. It builds up quite nicely, but it's too short to really do justice to your abilities. I don't see why you made such a short track for a podcast. If you made a longer track, with variation of style, then more people would take notice (because currently by the time the track registers in your mind, it's over).
Just a thought.
But in general, your overall work is excellent. I've been whoring your music to friends.
And on a tangent, I liked your username better as Zenon...
