You said you wanted a review of this... :)
You sound like you're using a lot of random notes for your synth. It gives a song less character if it doesn't have a cohesive thought. I think you could jazz the song up by having a harder drum line come in at around 41 seconds. That would really match the groove.
The synth that comes in at 1:42 is blah...
Overall, the tones of the synths are really nice, and with structure they can sound really cool.
Drop me an IM sometime, maybe I can fix this one up for you so you can take a look at how I fixed things.
