Heroic white mecha rising on ruined space battlefield

Original giant real-robot mecha design, widescreen 16:9, no text, no logo. A heroic humanoid combat robot with an original design, mainly white armor with blue, red, and gold accents. Sharp antenna-like head silhouette, glowing twin eyes, heavy chest armor, large shoulder plates, slim mechanical waist, powerful armored legs, rear thrusters and wing-like mechanical units. Do not resemble any existing franchise mecha; make it fully original. The robot is rising from one knee on a battlefield filled with debris from a ruined space colony. A blue-white Earth glows in the background, with destroyed battleships, sparks, floating armor fragments, and drifting smoke. The robot holds a glowing energy blade in one hand and a large angular shield on the other arm. Epic and serious atmosphere, heroic but slightly tragic, cinematic lighting, strong backlight, highly detailed mechanical parts, metallic texture, anime movie style, ultra-detailed, dynamic composition.
