Okay, I know this is a picture of Cerin Amroth and not the Field of Cormallen! But it is the closest of Allen Lee's pictures that I have found that evokes the feeling of this day in Middle-earth history. For Sam wakes up after eleven days of unconsciousness to find that all is well!

And then one blew a long trumpet, and they went on through the aisle of trees beside the singing stream. So they came to a wide green land, and beyond it was a broad river in a silver haze, out of which rose a long wooded isle, and many ships lay by its shores."
