Hello, Favio here, this is a decent work but the main flute sound feels inorganic, you can use some frequency exciter in the highs or use white noise mixed with it for get a more natural sound, combined with proper dynamic eq on the low mids you get a pretty decent flute. Vocals are really good but I feel like it needs to be more crispy and reverb, space time effect on this rap style so check that.
Drums are the less interesting part and that's not good, I don´t feel the bass of the kick kick so much, the 808 has dirty low mids and poor low end, the clap is very hi pitch, try send the snare pre fader to a channel and put a frequency shifter to add the low mids that way for more natural result. hats are a bit high, try to balance everything again with a reference song. The vocals in the outro have too much silibance, hope my feedback helps you. Please share this stems with me for practice:)
