This is Kristine AKA Michioreo123, a Deviant friend of Jetrashipper, who also made a cameo appearance in the fanfiction MC:SM Rewritten! She has made a lot of amazing artworks for MCSM, especially fanart of Nikki and the MC:SM Rewritten Universe, which is also not limited to AUs, comics, etc! so go check her out!

This is based on one of her appearances, which I can't find at the moment, but I like how it turned out.
