Your Art Travesty is so beautiful... I'm speechless! Frodo and Bronzino are a good match.:) Thank you for posting the poem as well; it's very moving.
Speaking of moving, I always found that the lines you quote:

I am too late. All is lost. I tarried on the way. All is lost. Even if my errand is performed, no one will ever know. There will be no one I can tell. It will be in vain.’ Overcome by weakness he wept. And still the host of Morgul crossed the bridge.

were awfully sad; I believe it's the only time we see Frodo weeping, and I think it's significant that he weeps about a story he's not going to be able to tell, and not about his own fate. I don't remember him weeping in Mordor.
