I like the melody at the beginning, but it sounds a little dry. I think you should add some more reverb. The chord at :18 is both too loud and rather dissonant. The bass riff at :36 definitely overpowers the celtic melody. I think you need to think more carefully about how you balance the volumes among different instruments. The transitory material in this piece is pretty cool, though, like the crash/sweep combo at 1:36. I wish you had varied the celtic melody towards the end of the piece a little more. Also, the guitar riff at 2:11 pretty much comes out of nowhere. Usually it's pretty jarring to introduce new instruments into a piece during the last 30 seconds, and this is not exception. Overall, this piece has a unique sound design and some cool melodies. I think you need to be more careful about how the different riffs connect harmonically, though. Keep at it, man. ;)
Thanks man! Love the feedback, I'll look to fixing those things. For the part at :36 was supposed to be bass driven while the Celtic melody is in the background.
Have a good day :)
