Amazing imagery! What a great way to describe fireworks.
"They wilt into burning embers," -I like the kind of comparison to flowers.
Well written! I enjoyed reading this!

Nice, very concise but also expressive. The description and imagery is good. I particularly like the "black satin." I wonder about the personification of "sullen water"... I don't dislike it, it is just makes me think. I only suggest that you not use "sky" twice, since the poem is short. Maybe substitute "the heavens" or avoid the word completely in one line. Very good poem.

Very short but a really good piece. Wonderful imagery, and there's an emotion and sadness to it I can't quite put my finger on. It paints some interesting images in the mind. Well done!
