The fact that you attempt strict poetry forms such as this one is credit to you.
I'm not sure if this would help?
Across tangerine horizon,
as dawn stirs remnant mignight hues,
shimmering curls of golden yawn,
wrap silent shadows, in pursue.
use the dawn to finish the first line that will rhyme with 'yawn'
'Sweeping zest of tangerine dawn'
Then 'stirs the remnants of midnight hues'
Daffodils sway with lively charms,
feathered colors fly over moor,
cuddling embrace of breezy arms,
bewitching - a new morn's allure.
Daffodils sway their lovely charms. *This would add to the needed plural.
I hope this is helpful, or at least aids the thought process.
