The track sounds pretty cool man. But I think your mix could use a little work if you don't mind me saying. Your strings sound a little muddy in the midsection, the bass kick defentily seems too high pitched and what's hitting the woofer notes isn't very sharp. And I think that $10 a minute...well it's not too bad of a price. I think you could tweak your string synth a bit too, the transitions between notes are a bit rough and it sounds a little canned. Have you heard of Edirol Orchestral? Great stuff for a relitively low price. But it sounds like you know your stuff in terms of composition and theory based off this track.
