The main sample is pretty basic, I really like what you did with it. I didn't really expect that spacey vibe which i enjoyed and the chops and hat work. Only thing i would've done is change the sound of the main synth to something more interesting, other than that mane it's a nice chill beat keep it up!
Nice and relaxing beat, kick&snare fits well, the reverb on the second one is nice and match's well. Bass line is interesting but discreet, and that is acceptable for your song proposal. Closed hat is okay, synth's were well explored, cool production man. Good for rapping and to another purposes too, like some video for example. Mix sounds balanced to me. Could you check any track on my soundcloud please?
I really like that loud reverby snare. Cool sound. The melody is nice and slow and chill. I think a singer would be really dope over the top of this. I do think it is a bit long to repeat that same chord progression the entire time. I did like the added high synth over the top at the end though.
