Very interesting. I think the black and white looks pretty gorgeous.

However, if I were to be super nitpick-y… Seeing that you said you were wanting to make it look like something akin to the Flash Gordon serials or Kurosawa’s B&W films, I feel like the color grading has a bit too much contrast. It makes it look more modern B&W rather than B&W from the 30s/50s. However, if you’re happy with it, I won’t complain!

Also, are you going to add grain onto the film? I’m just curious.
