bar 66 - 73 the notes are easy but just timing the triplets with the dotted notes in the left hand (whats it called? syncopation?)

here is the reference midi

as you can see, that some of the arpeggio is played quicker.

but I have a feeling that the rhythm for both left hand and right hand is more free. I dunno maybe for consistency sake I should practice with the left hand and right hand dead on.
