Wow, this is awesome. You're doing something with film and that's beyond words level great. I was gonna say some of those stills had a slightly Persona vibe about them to, then you mention Bergman as another influence for it and there we go. :cozy You've seen films from Tarkovsky, yes? That's what came out at me too, with the B&W cinematography and the locations. Always love to see inspirations like that, even if intentional or not.
Already intrigued by what you've shown. Can perhaps see how you mold it in the vein of the ever terrifying Winkie's Diner scene from Mulholland Dr. once it's laid out and watched. Would like to see it once you can finish it up, if possible.
