Kneeling Blonde Knight at Castle

Create a cinematic, realistic medieval fantasy portrait, with the central figure being {argument name="main character" default="A blonde female knight"} She kneels in the center of the stone castle courtyard, facing the camera. She wears highly polished, ornately decorated silver full plate armor, embroidered with gold filigree, and heavy gauntlets, shoulder armor, breastplate, thigh armor, and knee armor. A deep navy blue cloak or robe with delicate gold embroidery drapes behind her. Her wavy blonde hair falls over the armor, but her face is deliberately obscured by a simple skin-colored rectangle, revealing no facial features. She holds a long, straight medieval sword horizontally across the frame, its golden hilt on the left and its sharp tip pointing to the right. Behind her stand four guards in reflective silver armor: the tallest on the far left, the shorter one on the left-center, the shorter one on the right-center, and the tallest on the far right; their faces are also blurred or obscured by simple skin-colored rectangles. Behind the crowd are three tall, dark blue banners with gold decorations: one near the left edge, one on the left-center, and the other on the right-center. The background is the magnificent gray stone castle exterior, complete with towers, arched windows, battlements, and arched entrances, slightly out of focus. Shot from a low horizon angle, with a 2:3 aspect ratio, central symmetry, shallow depth of field, bright natural sunlight, realistic shadows on the cobblestone pavement, and highly detailed metallic reflections, it possesses an epic, fantastical realism style. There are no modern objects, no text, and no watermark.
