i started looking at hand drawn textures. visually they look good depending on how they are drawn . some could give that creepy look and when its dimmed down - it could be subtle and colorful.
The "Backwater Gospel" is a short animation and an example of how this 2D texture is used to give the creeps.
Another animation that uses the same art style is "Path of Hate". A short animation based on an historical war activity that occurred. visually comparing with Backwater Gospel it is noticeable that the texture is hand - drawn but not as thick and grainy, maybe more hand shading.
expanding on the visuals i also admire the style of black and white. since my story is about the past and someone who passed away i would prefer using black and white with a bit colors popping e.g everything could be in black and white but a particular couch that i would remember was red. that color would stand out when its in a scene. an animation that uses this style was "Paper Man" animated by Pixar. it also integrated a subtle style or flow of 2D elements, not sure if its the texture of the way the animation was rendered. it would make sense and have more meaning to the animation if it was black and white.
