At Pre-brekdown at the 3/4 section use repeatable dotted 8ths to staccato a chord. Consider a BPM increase to 172. Alternate the passing and neighbor tones at the 3/8 part in breakdown section. Should develop twin guitar sections and leave the breakdown for last as I have no ideas on how to proceed with the rhythm. Possibly the twin guitar will help.
Take small steps and don't get paralyzed by the big picture!
