Does anyone here know Shuumatsu No Valkyrie?
If no one here knows this Manga/Anime, it's about a Tournament between Gods and Humans called Ragnarok, which is meant to prevent humanity from being wiped out by the gods.
This story depicts fights between a god and a famous human, such as Adam, Jack the Ripper, and Nikola Tesla, and between gods like Zeus, Thor, and Anubis. The manga/anime is interesting in how it portrays the fights and backstories of each character, along with other well-known characters who appear, and features incredible character designs—not all of them, but reimaginings in their own style.
But my real question is whether you're interested in watching the manga/anime and if you're interested in making fan art. I can let you know in the comments if you'd like to request art based on some ideas I have, such as having a certain historical or divine character, or someone from another franchise, fight each other. Let me know in the comments.
