I suppose it'd be unfair to judge it on a personal level, I personally feel like it's lacking in substance, and the tonality isn't really of my tastes--
Beyond that, on a technical level, the major chords and the limitation to 3 semitones of variation leaves some unsavory dissonance with the melody. I see that a good amount of work went into putting this together, but it's kind of amorphous. The mastering leaves you unable to pick out any of the instruments, and as a loop it's kind of truncated. Not that it's awful, the equalization with the end of the song just doesn't match up with the beginning, and it leaves it feeling cut off, rather than a smooth loop. With some polishing it could be, at least from a technical standing whole lot better.
