Watch the Wazamataz Breakdown: 6 online guitar lesson by Richard Gilewitz from Fingerstyle Narratives
Bars 38-53 contain another measure that should particularly grab your attention when trying to play the piece smoothly. In measure 38 watch for the fluidity of sounds created on strings 1 and 2. I suggest slowing that portion down and working with a metronome. Same thing with measure 40 as you must be sure to time evenly the movement on string 6 from fret 2 to 4 to 2.
