ภาพสเก็ตช์ดินสอขณะกำลังวาดพร้อมรูปอ้างอิง

A realistic graphite pencil sketch in progress of [a beautiful young girl with short messy bob hair, freckles, hoop earrings, and a soft closed-eye smile], resting her cheek on her hand. The drawing lies on [a white drawing sheet] surrounded by scattered pencils and art supplies. Next to the sketch, a smartphone displays the same girl as a reference photo. An artist's hand is actively drawing the portrait with a graphite pencil. Monochrome black-and-white palette, detailed graphite shading, realistic skin texture, soft indoor lighting, cozy workspace atmosphere, [top-down angle], calm and intimate mood.
