荒蕪戰場上磨劍的孤獨騎士

A solitary knight, clad in battered armor, meticulously sharpens his sword on a whetstone. Sparks fly as he works, his gaze fixed on the blade. He is positioned in the center of a desolate battlefield, with the remnants of war scattered around him, but his attention is solely on preparing for the next encounter. This is a dark fantasy concept art piece, rendered with a photorealistic technique and dramatic, moody lighting.
