Decent
I did like the bass and drums, but the synths were pretty boring and repetitive. I think you could have made it more upbeat because at times it seemed to drag on and just sound unmelodious. But good job for the first time using Reason, I know that my first song on Reason 3.0 wasn't great. Reason 4.0 is a great program, and with practice you should get better.
And also, check out my newest song Futureform if you have time.
