Extant source can be found at https://www.pixiv.net/artworks/78270997 (3 of 5). MD5 does not match, but resolution, file size and EXIF data are identical, and under close visual inspection I could find no differences.

The Danbooru version contains the phrase

:xmptk="Adobe XMP Core 5.6-c142 79.160924, 2017/07/13-01:06:39        ">

while the Pixiv version contains

:xmptk="Adobe XMP Core 5.3-c011 66.146729, 2012/05/03-13:40:03        ">

That seems to be it.

Your work is mind blowing

@Cherry_Ayu Artists very, very rarely visit this site. Go to the source or the artist wiki page via the "?" link next to their tag to find places you have a chance with communicating with them.
