Congratulations on trying to write a sonnet. But I stress 'trying'. A sonnet is 14 lines of iambic pentameter - five iambs per line, dum-DUM dum-DUM dum-DUM dum-DUM dum-DUM
("O how unlike the place from whence they fell")
Sometimes the pattern can be varied with a falling DUM-dum trochee
("Earth has not anything to show more fair", first foot)
sometimes with a flat flat dum-dum spondee
("The frost performs its secret ministry", last foot)

What you've written doesn't come close. The pattern of stresses is different in every line, and in most cases there are four rather than five. Also the rhymes are appallingly forced - 'sire' isn't a synonym for 'horse', 'debase' isn't a noun and a horse doesn't have a 'face'.

Frankly, I don't think poetry is your metier.
