An ysis and decomposition of the crows last stand by ted hughes?

Hi im really in need of some help with this poem. Poetry is not my forte so i really need a lot of guidance. I need a well put ysis and a decomposition of this poem, a decomposition is like a pastiche, you must create a new poem following similar styles and changing words to recreate a new meaning to the newly created poem. I just need somewhere to start right now because im literally just stuck. I really appreciate all your help, best well put ysis and idea of composition gets an easy 10 points
