It's really an amazing piece of art!
But I have kind of bad news for you
Here, look at this:
I knew she was imitating your style but i didn't know she would copy an entire piece of art
She put a link to your deviantart in the description but i'm still showing it to you because, in my opinion, this is bad
But it's up to you to tell her or not, or to consider it plagiarism or not
I'm just warning you
