Well, it's about five years late, but I was wondering if I might use this picture as a cover-art for a story I wrote all the way back in 2014, Changeling to Fit the Role. I may have used it initially on my FiMFic account with just a source link, but it's easier to ask for forgiveness than it is to ask for permission, I guess.
Anyways, I'd be posting it on my FA and possibly DA profiles in a cropped thumbnail format, and would naturally source the art back to the original posting here (or whichever site you would prefer).
You can find the story here, if you'd like to take a gander at it yourself: https://www.fimfiction.net/story/172645/1/changeling-to-fit-the-role/shes-a-changeling-queen-young-and-sweet-only-seventeen
Thank you for your time :)
