From my little research, probably Chang'e since she has dark hair. But she has purple, not red eyes.
I also downloaded the image and uploaded it to Yandex Image Search but it only got me results like "Костюм персонажа" and "Дизайн персонажа", which in my limited understanding of Russian means "Costume person" and "Design person" along with stuff like "anime". That route does not work well.

Depiction is consistent with JP fandom portrayals of a human Junko back when she was still a living human. This depiction is usually called Xuan Qi/Gensai, after the original name of her historical counterpart (Chun Hu/Junko/Pure Fox being more of a title or epithet).

This fan version of Junko almost always has black hair because the historical Xuan Qi was noted for having particularly "beautiful black hair". Usually she still wears the anachronistic dalachi because that's pretty much Touhou Junko's signature headdress.

Image above also seems to depict Hou Yi's killing of Junko's son Bo Feng. Note the arrow (Hou Yi's preferred weapon) and Junko's shocked expression, and her hands being bound, which is consistent with how Hou Yi in historical folklore murdered Xuan Qi's husband to marry her, then killed her son Bofeng later when the latter attempted to rebel.

This event wouldn't fit Chang'e, who in folklore got better treatment from Hou Yi, and also didn't have anyone she's close to being killed next to her. Chang'e is also generally depicted in Tang dynasty clothing (also anachronistic) and with her signature Flying Immortal Bun hairstyle (two high buns or hair rings, or some kind of simplified figure eight ala Kaku Seiga) instead of having straight hair like Touhou/fandom Junko here.
