I like the instruments and mood. I think you need to work on your mixing a bit, though. The drums could sound clearer, and they will if you EQ the instruments more. Especially make sure you get rid of the low tones on all of the instruments except the bass and kick - it can get really muddy and distorted down there. This track is pretty repetitive, but my main problem with it is that there are almost no transitions. You might even be able to get away with just sticking a simple crash in there occasionally, but some more work with the drums or (if you'd prefer) sweeps and risers would be much appreciated. I do like a lot of the riffs and stuff in this piece, though. It has a lot of potential. Hope this review was helpful and keep at it, man. ;)
