Hi I'm gonna be real honest here, i don't like the "Ohh its awesome keep up the good work" type of review because i think that wont help you.
First, Technically speaking your song doesn't sound bad, i think the mix is pretty decent, maybe a little more bass, i really liked the hats by the way.
Second, Musically speaking i think you fell short, your song doesn't have a melody nor a chord progression just some tones here and there, at the 2:00 minute mark it seems like the song will take off but it never does, basically your song doesn't have a unique factor, i think in order to music for be liked it has to be memorable and for that to happen you need melodies and chord progressions, i do like the kind of dark vibe. I m not really familiarized with old style dub maybe that genre its all like this so take that in consideration when reading my review.
