I'm glad this thread got bumped because I skipped over it when it was first posted. And I'll admit why: you called it "electronica". I just don't like most electronica. The bulk of the genre consists of tedious drones, automated arpeggios, drum machines on autopilot, squashed and submerged in a reverb bath. The musical equivalent of boiled cabbage.
There needs to be a new word to describe electronic music that's NOT boiled cabbage. Whatever such a new category might be named, I think Neptune's Oceans qualifies for inclusion.
Yes, there are some noticeable artifacts in the beginning. I'm not sure what it is, perhaps a click being propagated by reverb. I'd zoom in on it and try to determine what it is, and perhaps automate it out.
A suggestion for adding some interest: keep the percussion but inject some unexpected percussive ear candy here and there. Something either very deep (e.g. orchestral bass drum) or bright (e.g. triangles, finger cymbals). Tablas or bongos might go well with the sitar theme. Whatever you stick in, make it brief and unexpected and panned out of center, in contrast with the steady rhythm that's already there.
