Great mix of instruments. The bass line that runs throughout holds the piece together and gives it some structure as the other instruments shift and change around it. You're string sounds are very realistic, as in fact are most of your instruments, the overall sound production is great. I think perhaps the bass is a little loud at parts, but mostly the mixing and mastering is good. The song is fairly repetitive and whilst you've varied the instrumentation the general chord pattern and melodies remain fairly static. Overall i think it's a nice piece but the song structure and composition needs a little work. The ending is very abrupt too.
for the ending i was editing so the file would be the right size and that got cut without me even noticing.
