Hi Glenn,
Just a couple thoughts on version 2--
1. It seems to me the poem, as an extended metaphor, is weakened by beginning with "like." How could you enter the poem within the metaphor rather than using a simile?
Unless you intend for the poem to NOT be an extended metaphor, in which case I would say it still needs to go somewhere, not stay, still, on mere description.
I just read your recent comments that you did not intend an extended metaphor on the models, in which case I would suggest that the poem is in need of another metaphor, story, or character to attach to. Or perhaps, a clever title. As is, I do not get your stated intention from the poem:
"I wanted to suggest that the moments in our lives that are filled with excitement, glamor, and glory (for which I use fashion models as a vehicle) are fleeting, purchased with long years of suffering, and impermanent."
2. "joyful, glorious" seems to me to be too many adjectives and also weak/vague ones, especially for a final line.
Looking forward to seeing where this goes.
I'm not at all fond of mayflies. It would be interesting if you could make me feel any empathy for them.
Take care,
Chelsea
