Yes, I figured. I recognized some of the beats, but for a second there I thought you're a sick fucking producer haha. Anyways, you got good taste in beats.
Can you, please, tell me for how long are you rapping?
You have a really nice flow, good timing (rythm) and, how do you say, pronunciation? Like, you speak/rap cleanly, so kudos for that.
But one thing I feel you should try working on is your voice control. Sometimes you "talk too much", if you know what I mean. Try finding the right balance between plain shouting and plain speaking.
Overall, this def sounds good enough for a first mixtape. Has potential.
