Avoid including any background scenery or other characters; the focus should solely be on the female knight. Ensure there are no modern elements or anachronistic details present in the armor or surrounding the character. Do not deviate from the described posture and attire of the knight, especially the glossy fleur de lis symbol on her armor. Avoid any cartoonish or exaggerated proportions; the anatomy should be realistic and accurate. Ensure the sketch does not appear too clean or digital; it should retain a hand-drawn, rough aesthetic. The image should not be rendered in a resolution lower than 4k, and the focus should remain sharp, particularly on the knight and the fleur de lis symbol.
