Hi!
I agree that Reason 3.0 is a very capable program and programming my own combinator patches with subs and mallstroms is one of my hobbies actually

(I whas #1 in the recent Big Lead contest

)
But about your track.. I think it starts to shine at 2:07.. but
I have the feeling the mix could be improved. Some instruments are realy far away in the mix, and perhaps you did this on purpose, but sometimes there are simply to much instruments at the same time, making it sound crowded and especially the softer instruments don't have enough energy to be heard..
The mix also lacks a little bit "punch" or loudness..
Disclaimer: Everything is just my humble opinion and I'm not a pro!
But I like the track
