pencil sketch illustration of a stealthy woman in a ninja-style outfit. She should be depicted in a dynamic pose, such as mid-leap or crouching, with flowing fabric and traditional ninja elements (e.g., a masked face, hood, katana strapped to her back ). Use detailed shading and cross-hatching to emphasize depth and texture, giving the sketch a raw, hand-drawn feel. Include subtle environmental hints like faint bamboo stalks or misty shadows in the background to enhance the ninja theme. Focus on contrast between light and dark areas to highlight her sharp, focused expression and agile posture
