Beat is nice, I liked that a lot of things going on in the stereo space, but the mix is definitely not overcrowded and actually is interesting to listen. I think I would check another acapella on this beat, moreover, vocal sounds to me a little bit like from behind and should be in my opinion pushed upfront. Moreover, I would suggest arranging it with more distinct intro and chorus then it would be a really good quality and complete track.
If you'd like please let me know what you think about my tracks (see signature for that) as well as I would appreciate if you'd take part in my experiment described below:
I like the melody and mix. Maybe the vocals gets a bit buried in the mix. Aside from the mixing of the vocals though, I think they fit the beat well. Overall the beat is really nice and atmospheric.
