I think you both did a wonderful job, and theres not much I can really go into detail with on this.. Great work with the rhyme scheme and fitting the form to the T. Your descriptions were beautiful.. if I had to pick one line I really loved it would have to be
'The foal, her miniature shadow...' I loved how you said it was her miniature shadow.. a great description and unique way of using shadow to describe how they are alike in their physical characteristics.
'Which grows till time divorces them,'
`I also liked this line for the fact of the way that 'divorces' was used.. havent quite heard it used that way before but it worked out really well.
Theres not much I can really truly say for you both, but great work. I thought it was beautiful.
You both created a masterpiece that is so appealing to all. Your descriptions blew me away, they were so real in my mind and your unique wording held my attention. Great job with the rhyming and staying in format, such creativity was shown and you both surprised me with this one. Not much else to say though but well done. This was a brilliant write, so keep it up!
