Your silver tongue seeks
To find itself upon the golden apple
Aspire to a new Aphrodite
Arm companion to the rich and mighty
Sat upon a victor’s spoils
For when the threat is in your eyes
Hera’s jealousy burns and boils
This silver tongue gave your rise
By the same will it be your demise
I thought the rhyme compromised the piece. Rhymes like rise and demise seem forced and give this an unnatural rhythm since the rest of the piece is fairly void of them. I think that it's more so you chose them for assonance; maintaining you "eyes" sound as in eyes, demise, Aphrodite ect. Overall I enjoyed this but it felt a bit fragmented the jumps from line 4 to 5.
I also think seated works better than Sat in "Sat upon a victor’s spoils" You'd weaken the assonance a little but it seems more natural unless of course she is no longer sitting upon victor's spoils. I don't know much more than a basic over view of Greek mythology and it's been ages so I'm not help there. do what you will.
