This sketch is based on the Legend of Zelda. It's modeled after the amalgamation of the official Legend of Zelda logo, the symbols on the wall of twilight, the design to the twilight portals, and the pattern on wolf Link's forehead.
The idea of this pattern came from a side project I've been working on with friends. It's title is The Legend of Zelda: Heroes' Tale, and it is a tabletop Dungeons and Dragons game, inspired by The Legend of Zelda. This image was designed to be the title image to the guide book to the game.
I used references to ensure that I was drawing this symbols correctly. The Legend of Zelda Logo was inspired by the cover of The Legend of Zelda Art and Artifacts book. The wall of twilight comes from the area that divides the Eldin Province from the Lanayru Province. It was the space with the widest viewing wall, making it the best reference point. The twilight portals appear all over the game, and they have similar designs. The wolf Link design was best seen on the Wolf Link Amiibio, launched by Nintendo.
I decided to keep this as a pencil sketch because of the complexity of the image. I felt adding ink or color would distract viewers from the design itself. This design was drawn at on a 14" x 17" page, with a border thickness of 1".
