The sample/pad sounds awesome. Wish there was another instrument but it's dope enough on its own. Drums not bad. The switchup at 1:04 and the end is sweet.
The mix is quite lo-fi and the melody is a bit of a haze but I actually like this because I listen to music like this. I don't like the beat switches though - they felt very disorientating to me, in a bad way. I would rework this so that there's a good coherent flow between one section to the nex.
Good stuff. I like the transitions and pads used - if the rapper would work with the beat something truly nice can come out of it. I feel that there's too much of low-mid in the stereo making the mix muddier. Anyway, really cool and minimalistic beat.
