I used a reverse google image search and found it without much effort, either way, using a DA model without express permission is against policy:

"Furthermore, images from websites such as DeviantArt, Pixiv etc. are not public domain images by default, it is down to the artists themselves whether or not they can be used other people, even under Fair Use terms."

- Image Policy

As the artist Harpiya does not explicitly state that their images can be used by anyone, you'll have to contact them directly.
