I'm unsure if this is even possible in votv's engine but I feel like a really cool stylistic choice could be making stuff like dynamic shadows pixelated.
I haven't seen it done anywhere except (shamefully to admit this but minecraft's vibrant visual shader), But it fits minecraft's pixelated sorta style stupidly well and maybe could work in votv.
but I am no artist so don't take my word and I don't know votv's engine limitations
