Iono what the dude down there is talking about not hearing the blues.
This IS the blues, and its beautiful. The flourish at 0:10 put a knowing smile on my face, heh. That was some song, man!
Long live minor blues! Try and get some really classic stuff in there:
ii7(b5) - V7(b9) - i(Ma7)
Its the classic minor 2-5-1, but use it when you are modulating between chords in minor blues, you will cry listening to it, lol. It's amazing. I ought to record some of my jazz stuff. :p
