adequate.
i too find this a bit fast. i enjoy the cover and it's nice to listen to, though i believe more could have been achieved.
perhaps you prefer simplicity but i would suggest more depth, more variation. i like the choice of instruments already, although more could have been introduced to add to the melody and chorus. i know this is a short loop and not much could have been done. should this have been a longer loop, perhaps even a full song, you could have introduced new elements as you progressed here and there. it is the new elements and variation that catches your attention and ears.
you have chosen an amazing song to cover, and this is quite nice to listen to. i only wish you had done more than what is here. Cheers!
