Returning the feedback. I'm actually familiar with the original.
The beat is crisp, but the main (and only?) synth is quite ambient and gets repetative. I feel it's good as a filler, but the beat would sound more full if you added a higher frequency instrument and a mid/lower mid frequency one with a good amount of variation to catch the ear. Besides that, the drums should cut through the beat more, as the kicks and snares are lackluster compared to the instruments.
Also, compared to the original beat, the percieved tempo of this beat doesn't seem to match the vocals, so if you were to add more instruments as leads, I would personally make them at a faster tempo, or at least highlight the high-hats so the rappers vocals match them better.
Overall, it's a professional sounding beat, and it could easily be a hit with the addition of a few more instruments/brightening up the drums, and perhaps a few conceptual changes, but that's just my opinion. Cheers!
