Needs improvement
I'll start off with the good stuff:
-The bass sound is pretty nice sounding. It sounds like either you spent a lot of time tweaking the instrument to perfection, or you have a good taste in presets.
-The drums were pretty good. They actually sounded familiar, like some .rex file form the Reason soundbank.
-There were actually a couple of nice variations and progressions in the drums, but not enough.
BAD STUF LOL BOO
-Right away the bass hits me with... A RANDOM MELODY! Try to spend more time on the main melody before you think "ok this sounds good enough".
-The harmonies sounded horrible. It's probably just the synth, but those higher octaves didn't go well together with the lower bass part. It would have been much better to put those higher notes on another synth.
-The panning bass is distracting and unnecessary.
-The drums are okay for an intro or something, but they get boring after a while and begin to sound like a cranky, poorly-mixed muddy old breakbeat.
-It was drums and bass. No atmosphere, no background, no pads, no fx samples. Thats pretty damn boring.
-The overall progressions sounded awkward and random. Each part didn't flow into the next, it just stopped and started randomly.
1/5 I don't mean to sound like an ass, I'm just trying to help.
