What elements or symbols would Shadowhunters fans love to see on a handmade book cover redesign?

Hi everyone! I’m redesigning a cover for Shadowhunters (any book from the original trilogy or all three combined) using handmade techniques like collage or papercut.

I’ve been researching different elements to include, but I’m kinda confused about which ones to highlight the most. I definitely don’t want to end up putting just a single rune in the middle with nothing else around it.

I want the cover to feel authentic and special, with meaningful symbols and details that really resonate with the fandom.

Could you share:

• Symbols, runes, or objects that are important in the series?
• Characters or scenes that really capture the essence of the books?
• Any small details or “easter eggs” only fans would notice?

Specific examples would be amazing, please! Thanks a lot!
