Rhymes are perfect. Diction is a little uncertain in some places, like
This afternoon you can be dead certain
I'll be outside sipping sunshine closing them curtains,
Could have been remedied with a stop-and-go flow like
This afternoon... you can be... dead certain
I'll be outside sipping sunshine, closing them curtains
Because as fast as these bars are, short-long isn't gonna do them justice. Maybe revisit this flow with that in mind. Reading through I was almost feeling a 123/123/12 vibe. Listening, you blazed through those rhymes.
Otherwise, I don't know why you're warning us about quality. These bars might not be platinum, but they fiiiiire.
Ps, what Kieran said.
