The Fairy Roses

I have taken an oath not to divulge any information on the last book in the best series ever (in other words, I'm not allowed to spoil it for anyone), so I'm afraid that I can't describe this picture...at least not until those I know who want to read it have read it, or the 1st of September (whichever comes first).
Sorry about that.
All I can say is that it has something to do with the last book in the most amazing series of books ever (Harry Potter fans will probably disagree with me on this, but we're all entitled to our opinions).
Oh, and I kind of have a song that I feel really goes with this piece, or, at least, what it is about:
"The Last Day On Earth", by Kate Miller-Heidke [link]
Any questions asked about what the picture is about will be neither confirmed nor denied, and answered with "I have taken an oath not to divulge any information on the last book in the best series ever (in other words, I'm not allowed to spoil it for anyone), so I'm afraid that I cannot reply truthfully to this comment."
Also, no one can spoil anything about the last book on this page. I will not allow it.

Best series ever/most amazing series of books ever: the Artemis Fowl series. Everyone must read it.

Oh, and this is fan-art, by the way.
More to follow.
(hah hah. I just quoted the fourth book in the best series ever)
