My first comment is why is the guitar so far back and too much verb.
It is an interesting progression, lots of dominant ninth's and then the minor chorus, cool.
I think a rethink of the mix would help.
A more active bass line would also liven it up. I like the concept but it almost sounds like a phyrgian jam instead of a tune.
Emphasize the melody, and I miss the restament of the change at around 25 seconds in. Keep the double stops, awesome.
I know this is a work in progress, just tryin to help.
