The structure of the Petrarchan sonnet goes like:
A
B
B
A

A
B
B
A

C C
B B
E C
this is an example of one

In what bright realm, what sphere of radiant thought A
Did Nature find the model whence she drew B
That delicate dazzling image where we view B
Here on this earth what she in heaven wrought? A
What fountain-haunting nymph, what dryad, sought A
In groves, such golden tresses ever threw B
Upon the gust? What heart such virtues knew?— B
Though her chief virtue with my death is frought. A
He looks in vain for heavenly beauty, he C
Who never looked upon her perfect eyes, D
The vivid blue orbs turning brilliantly – C
He does not know how Love yields and denies; D
He only knows, who knows how sweetly she C
Can talk and laugh, the sweetness of her sighs. D

in this sonnet there is one metaphor ” she is an angel”
in this poem i think it is about a women being described as a wonderful person
there is no volta in this poem
my haiku:
with a ladies shape
they will always look pretty
and that’ll never change
