I hear something really weird in the intro, and it sounds like it's majorly clipping. Intro is really muddy. Some sort of low end drone is cluttering things up like crazy.
Not sure what that is at the start but if it's intentional it's great. On my earbuds it sounds like it's coming from the back of my head. If it just wasn't panned slightly to the right...
The bass sounds like one long note. Can't hear the plucks at all. Some neat wide swells but they don't come off in a pleasing way. The alto sax has a few notes that had my ears hurting as well.
Most of the playing is too mechanical. Was it all moused in? If you can get a midi keyboard and try to play a few things then it would sound a lot more natural. Overall probably not quite ready for Mod Review just yet but this would be very enjoyable with some more development.
