The beat is a little simplistic, but moves the piece along nicely. The ominous melody is cool, but it would've been nice to have some additional harmonies in there - bass, back-up melody, etc. - before 1:26 or so. I think the main riff sounds really indistinct in the mix, which is probably my main problem with the piece. I'd suggest removing some of the reverb and delay effects to add clarity. It's possible that they come with the instrument you used, but I think having fewer mastering effects in the texture would add some clarity to the mix. I hope you continue to work on this, though! It's a catchy tune with a cool atmosphere. Keep at it, man! ^^
