great track~
Well.. I was going to make a more complete review but adompeace said most of it already :)... Then again, this is a great track, but I've liked others better.
I think I understand the feeling, I've released tracks myself which I've really enjoyed making and got the feeling that something was acomplished, something new, something improved, kinda hard to explain, but my only guess is that sometimes this things can only be felt by the composer/producer himself or someone really really in touch with his work (or even his feelings), so I would get feedback like "yeah it's cool... but your track *title_here* is still my fav from you...", in the end the taste of the listener plays a bigger role for feedback :).
The piano intro lacks something, I am not sure what exactly, I find it too simplistic but that my have been your purpose. The synth was just great IMO, and I totally agree that this track deserved a more energetic climax :).
Cheers!
