Some cool ideas. I really enjoyed the pads in the background and the beat. You should try modulating keys to generate continued interest, and using volume dynamics to create contrast. Lastly, the sound sort of implies Dorian Minor, but that chord at the end of the melodic motif has a b6 which kind of clashes with the vibe, try raising that weird note up a semitone to the natural 6. Keep getting those ideas out.
