First of all, Sylvia, I know nothing at all about Sylvia Plath's "Wuthering Heights" (nor what it might have had to do with Bronte's work, about which I also know nothing)
Secondly, your rhyme scheme nearly follows one of the two typical rhyme schemes of the
Petrarchan Sonnet, namely
abba abba cdc cdc, though your final triad goes
dcd.
Thirdly, most such sonnet begin with a question or proposition in the opening octet and closes with an answer or resolution in the closing sestet. I'm not sure yours does, but frankly that is of little consequence to me!
Fourthly, almost all such sonnets are written in iambic pentameter. The THRUST of your lines are iambic, but their length varies greatly:
I’ll just dream these lines, since you’re no longer here; - starts with trochee, 11 sylables
Your voice, your laughter and your soul - iambic, 8 syllables
Are sunflowers in the summer air; I know you stole - varied meter, 13 syllables
Their light to fill my waking hours with Irish cheer. - iambic, 12 syllables
My love for you is wedded to the morning’s - iambic, closing in feminine ending, 11 syllables
Elemental time, a coffee cup and friendly chat. - trochee, 13 syllables
I spy the raindrops sparkling on your jaunty cap - iambic, 12 syllables
My heart recalls each time the doorbell rings - good iambic pentameter w/ one variation
Three times. I hear the lively flute you’d play - good iambic pentameter
For many radiant years; and in the knowledge - IP w/feminine ending (11 syllables)
That you were going to die, I prized Commencement Day, - iambic but varied, 13 syllables
The artist in the park who sketched your image - IP w/feminine ending (11 syllables)
On tawny paper. I know God shows the way, - iambic to trochee, 11 syllables
absence, instants in life’s blessèd pilgrimage. - trochee to iambic, 11 syllables
Well, there is my first look. Not sure whether that helps or discourages, Sylvia.
Lightly critiquing, Daniel
