Prompt: 3:2 aspect ratio, continuous seamless vertical composition of a dark sci-fi battlefield, no hard split or visible seam. A colossal pure arachnid spider-like war machine looms in the upper portion, towering over a scorched battlefield that occupies the lower portion. The entire image is one unified scene with consistent lighting, atmosphere and perspective.

Upper portion: partial view of an extremely massive eight-legged spider war machine, pure arachnid morphology only, no humanoid features whatsoever. Large central cephalothorax and bulbous abdomen structure, eight thick multi-jointed mechanical legs radiating outward. Geometric angular matte black and dark steel armor plating. Numerous clustered missile launchers densely packed across the dorsal surface and leg joints, thick heavy energy cannon muzzles protruding forward from the front section, glowing crimson sensor arrays and optical clusters. Brutal industrial biomimetic design. Only the upper body, weapon systems and upper leg segments are visible to emphasize overwhelming colossal scale. Low-angle framing making the machine feel impossibly tall and oppressive. No bipedal form, no humanoid torso, no arms, no human-like head.

Lower portion seamlessly connected: scorched battlefield with cracked concrete, debris, shell craters and scattered metal wreckage. A lone small soldier seen strictly from behind, standing firm in the foreground, holding a man-portable surface-to-air missile launcher (Stinger-style) aimed sharply upward toward the spider machine. Full tactical gear and helmet, determined posture. Strong low-angle perspective with vanishing point leading directly up to the massive war machine above. Long dramatic shadow of the soldier stretching toward the machine. A single intense beam of light illuminates only the small soldier, while thick smoke, dust and volumetric fog rise from the ground and partially obscure the lower legs of the machine, visually connecting both halves.

Cinematic volumetric lighting, thick smoke and dust, oppressive and fateful atmosphere, dark sci-fi, hyperdetailed, 8k, masterpiece. The spider war machine feels like a living mechanical arachnid predator rather than any humanoid robot.

Avoid: humanoid robot, bipedal mecha, android, human-shaped body, torso with arms, human-like head, Gundam style, Transformer style, Evangelion style, pilot visible, full body of the machine, multiple soldiers, soldier face visible, hard horizontal split, visible seam, different lighting between top and bottom, bright colors, clean environment, blurry, watermark, signature, logo.
