To me, that pattern doesn't complement your existing architecture.

Below is a stencil I think would turn out a better result.

I like your stencil pattern, I saw the Etsy page with rooms done with it ... very boho cool. It is bold, but so easy to change if desired later on. I think it goes great with your decor.

I like the color in the pic you posted, and prefer satin. What sheen is the rest of the room?

I like it in the black and in the gray, too, but I don’t know enough about the rest of the room to see what would work best. What will the other wall colors be? What kind of furniture? Etc.

Thanks so much. Sheen in the rest of the room
Is matte. Accent wall color is Benjamin moore Rust & rest of the room is monroe Bisque.

Furniture is more like Pier 1/world market style
