okey, I like your beats (maybe some delays on the snares?) and the dark melo.. But I'ts a little to fast for me, maybe you can try to slow it down to 120 - 130bpm, and drop that bass a little so you have less destortion on your sounds. And to make it more interesting like you say, you can use some vocals and/or horns or something. BUT, you put work into it and I think this track is very nice for a first time with dub, so keep up ;)
