Fun fact: at first glance I read the title of this thread as "848 BPM Boom Bap"
and that got me curious not gonna lie.
But jokes aside, overall as it was already mentioned, pretty clean mix. I like that subtle sub bass (personally, I always struggle with sounds in this range so props for very clean, audible and round sub-bass). I like the sound of that cello/violin you used for the melody. The only thing that I would adjust is the arrangement - the beat gets a little bit monotonous after a while and even when I pictured an artist performing on it, I think it would still be quite boring in the long run.
So maybe try to vary things here and there. Also I would say that the kick could be slightly more exposed in the mix. But other than that it's a good beat in my opinion.
