This MIGHT be AI art, there's some oddities going on, such as her halo not being the right design, the two "sigils" on her arms being overcomplicated, and some other details that I'm not 100% sure on.
For now I'll tag it as such but if anyone wants to disagree, they can remove the tag.
Edit: Just as I was making this comment, someone already tagged it as ai-generated. What a coincidence lmao.
