Chevalier blond agenouillé au château

Create a cinematic photorealistic medieval fantasy portrait of {argument name="main character" default="a blonde female knight"} kneeling in the center of a stone castle courtyard, facing the camera directly. She wears highly polished ornate silver full plate armor with engraved gold filigree, heavy gauntlets, shoulder pauldrons, breastplate, thigh and knee armor, and a dark navy-blue cloak or tabard with subtle gold embroidery draped behind her. Her long wavy blonde hair falls over the armor, Show every face clearly with natural, detailed facial features. She holds exactly 1 long straight medieval sword horizontally with both hands at chest height, blade stretching across the entire frame, gold-accented hilt on the left and pointed tip on the right. Behind her stand exactly 4 armored guards in reflective silver armor: 1 large guard on the far left, 1 smaller guard left of center, 1 smaller guard right of center, and 1 large guard on the far right; their faces are also indistinct or covered by simple blurred skin-toned rectangles. Include exactly 3 tall dark blue banners with gold markings behind the group: 1 near the far left edge, 1 left of center, and 1 right of center. The background is a grand gray stone castle facade with towers, arched windows, battlements, and an arched entrance, slightly out of focus. Use a low eye-level camera angle, vertical 2:3 composition, centered symmetry, shallow depth of field, bright natural daylight, realistic shadows on the stone pavement, high-detail metal reflections, epic fantasy realism, no modern objects, no text, no watermark.
