The artwork adds so much depth and mood; I wonder if the visuals were planned from the start or evolved with the story.

The letter-writing and artwork evoke a bygone era, but also feel timeless. How did this style impact your connection to the characters?

The art feels so integral to the story—I'm curious whether the author or artist envisioned this as a graphic novel from the beginning.
