There is some lovely imagery in this poem. The golden dawn spilling into the Great Hall is such a picture of hope and joy which I think you captured really well. What really stood out to me was the third line, though.

Three words in all, but a world hanging in the balance.

That is really powerful. I love it.

I think you could work on the punctuation, perhaps. Instead of using a full stop at the end of each line, the flow could be improved by using comma's (or nothing at all) because the full stops make it a bit choppy. The repetition of the word "of" at the beginning of the lines gives each line a certain amount of emphasis in itself, so I don't think the full stops are necessary if you were going for a more blunt impact.

Hopefully that was helpful :) I think you've got great bones here, just tweaking the punctuation (something I struggle with in my own poems) could take it to another level.

I liked the gist of it, but I think it would be really good if it were a one-shot, about how someone felt about it. I liked the poem, and I feel really bad for critizing it, but I think that it could be MAGICAL if you made it, like, a one shot from Ginny's POV or something.
