when i draw sundown characters vs spire characters, sundown is definitely way more cartoony and stylized while spire leans more into heavier detail and shading. i also can mostly freehand all of the sundown characters and use more continuous/flowing lines while spire characters need more construction and detailed rendering when i draw them.
i think the reason for it is that my original idea for sundown was for it to be a concept for an adult action cartoon, decided to just make it a novel instead because i was too excited to start working on that idea. when i started spire i really wanted it to have a lot of complicated coloring which i.......kinda regret in the long run? but i feel like im too far to make any drastic changes to the art style without disappointing readers.
