The pulse repeated throughout gets a touch stale, I feel like it's possible to build a solid, long track around something simple like that (a la "Polaroid Girl" by Massive Attack) but I feel like the tone needs a little something more. I wish I could describe it better, but I dunno, haha. Maybe if it panned ear to ear slowly throughout the track, or some triplet grain shifting once in a blue moon, or jumped octaves it'd feel less stale.
But overall I really dig the track yeah!
