Solid beat here, B. I know it's unmixed and all, and this was just a quick track meant for practice, so I don't wanna go and give too many suggestions or anything.
But, that said, I thought the first half of the beat was nice; that vocal sample was pretty catchy and it sounds easy to rap to. However, I was't really feeling the second half of the track; it wasn't bad or anything, but I feel like the energy got brought down, if you get what I'm saying. It'd have been cool if it kept the same energy it had throughout the first half.
Other than that, it was a solid track. I'm listening to cheap headphones, so I can't really critique the mixing (and it's unmixed, anyways, so it'd be silly to judge that, anyways). Again, sounds easy enough to rap to, sounds decent just as an instrumental, too. Good work!
