Spoiler: @ 3SecondCultistI must admit that I was not familiar with the sestina. Nonetheless, I still believe it's nicely crafted. I don't really care about punctuation except when the style needs it (not the case here). Besides that, I only check consistency. Many have disagreed with me on this however...
Spoiler: @ TechwarriorYou are right, explicitly mentioning the 'shaking' prompt would be worse. It could have been hinted at more? nitpicking... I redacted the typo comment.
