overall, the bass could use a bit more "punch", by stopping the tones early
and pop/slapping
e.g.:

starting 0:58 :
instead of holding every note: slapping and then immediately stopping it (by
lifting finger of left hand sligthly)

1:07 :
(here, the tones are not stopped)

2—2—2p0—2p0—2h3|
s s s   s   s

(the s below means that the note above is slapped - this time not stopping it like above)

1:15
Main fun :-) - pop/slap action here, all notes stopped immediately except the last:

'p': pop note above
as mentioned earlier, this is shifted to the quint after 2 times and repeated

good

around 2:50
note actually stays the same on the guitar (bass does octaves), but this also sounds nice :-)
