Sketch to Vintage Horror Theater Scene

Using the provided sketch as the composition and creature-design base, transform it into a finished cinematic scene: render the sketched monster as a realistic grotesque insect-spider stage creature on the same circular pedestal, keeping the central pose, multiple legs, spikes, open mouth, and domed display/stage concept. Change the rough notebook drawing into {argument name="visual style" default="dramatic black-and-white vintage horror photography"} with high contrast, film grain, smoky atmosphere, and a strong overhead spotlight. Replace the simple sketched arch with an ornate theater proscenium: exactly 2 tall side curtains, 2 carved side columns, and 2 small floor lanterns near the stage. Add a formal theater audience in the foreground, seen from behind, with exactly 20 visible spectators in period eveningwear watching the creature. Make the image vertical, like a staged performance photograph from {argument name="era" default="the 1930s"}. Keep the mood eerie, theatrical, and grand; do not include notebook paper, pencil lines, handwritten symbols, modern objects, or color.
