Should be right, this is how I play it & it sounds perfect.
Tuned a whole step down. (Don't really have to though, still sounds good in standard or 1/2)

The order goes as follows:
Riff1 2X, Riff2 1X, Riff3 1X, Riff1 1X, Riff3 1X, Chord, Riff1 2X, Riff2 1X,
Riff3 1X, Chord, Riff4 1X, then Riff5 played over Riff4. Listen to the song & you'll
get it. It's simple but sounds awesome. All played in ACOUSTIC.
