Sounds great. love the instruments and overall song.
I like my songs to move along pretty quick which may not be your thing, but here are my views anyway!
The first 30 seconds are great. I would drop the big beats in at about 0:30 or at the latest 0:48. I think leaving it till 1:20 is too late.
The bass drum could be louder in the mix.
The main bass synth is too far left for me.
In general I would half the length of all your phrases to keep it more engaging.
You have lots of different arrangements there which all sound great but I feel it is lacking in different instruments.
Also I think the bass riff should jump into something more upbeat and quick mid song to liven it up. Like the bass in Waters Of Nazareth at 1:07.
Overall though I really like what you have there. especially the start. I think it's well worth the work.
Have you got any other stuff online?
PS - Have a listen to Bag Raiders (
http://www.myspace.com/bagraiders). It may be more pop than what you are going for but I love how much they fit into a short song. (Fun Punk, Nil By Mouth)
