Crimson Winged Giant Mecha | GPT Image 2プロンプトと調整メモ

Create a dramatic vertical anime mecha illustration of a colossal humanoid robot named {argument name="mecha title" default="Heaven-Piercing Crimson"}, standing in a powerful symmetrical front-facing pose on a futuristic circular launch platform. The robot is primarily {argument name="armor color" default="glossy crimson red"} with white, black, dark gunmetal, and small gold accent panels, covered in intricate hard-surface armor plating, panel lines, vents, exposed mechanical joints, decals, scratches, and tiny warning markings. Give it a sharp Gundam-like heroic silhouette with a horned angular helmet, glowing cyan eyes, a narrow face mask, broad armored shoulders, layered chest armor, long segmented legs, and two large arm-mounted weapons or shield-blade units; one forearm carries a long rifle-like cannon with a cyan energy strip, while the other has a large angular red-and-white shield blade. Add an enormous wing backpack made of six major blade-like wing assemblies: two huge upward red wings, two wide horizontal red-and-white wings, and two long downward tail fins, all edged with white and gold pieces, creating a phoenix-like aerial form. Use a low-angle camera looking up to make the robot feel gigantic, centered composition, dynamic perspective, crisp cel-shaded anime rendering with realistic mechanical detail, high contrast sunlight, glossy reflections, and deep shadows. Set the scene against a bright {argument name="sky setting" default="clear blue sky with scattered white clouds"}, with a distant futuristic base and horizon below, emphasizing scale and grandeur. Style it as a premium Japanese giant robot poster, ultra-detailed, clean line art, vibrant colors, cinematic lighting, no visible text except optional tiny technical markings on the armor.
