Generate a highly realistic, full-body depiction of a female White scars Assault Space Marine in Warhammer 40K-inspired power armor. The armor is massive but proportioned to fit her strong, athletic yet feminine physique, featuring reinforced plates, mechanical joints, glowing energy lines, and intricate engravings. Her face is visible, showcasing battle-hardened, determined features, with brown, slightly disheveled hair tied into a high ponytail that spills out of the helmet, which is perched to the side. The armor is adorned with imperial eagles, skull motifs, and weathered purity seals fluttering from the chest and pauldrons. Battle-worn scratches and scuffs cover the armor, adding to its gritty realism. She wields a massive, detailed bolter with heavy ammunition feeds, her stance confident and unyielding. The background is a grimdark battlefield with smoke, shattered structures, and distant explosions under a stormy sky, enhancing the dark sci-fi aesthetic. The scene should emphasize the imposing scale of her armor and the raw power she exudes.
