Fine-Art Pencil Sketch Portrait with Orange Circle Backdrop

Using the attached photo as the direct reference for the face and likeness, generate the following: Create a hyper-detailed fine-art pencil sketch illustration of the person from the attached photo, seated on the edge of a rough concrete block. Aspect ratio: 4:5 vertical portrait. Camera angle: eye-level, straight-on front-facing shot, camera positioned directly in front of the subject at a fixed medium distance, full figure visible from head to feet, subject slightly off-center within the frame. Pose (locked, must match exactly): seated on the edge of a raised concrete block, one leg bent with the knee raised and foot resting flat on the block, the other leg hanging down with the foot resting on a lower ledge, elbow of one arm resting on the raised knee, chin resting gently on that hand in a relaxed thoughtful pose, torso turned slightly to one side, head tilted slightly, gaze directed off to the side and upward, calm and contemplative expression, not looking at the camera. Eyewear: round-frame sunglasses. Hair: styled naturally into a loose textured updo with soft loose strands framing the face, matching the reference photo's general hair length. Clothing: a loose white button-up long-sleeve shirt with sleeves rolled up, worn underneath a pair of denim overalls with straps over the shoulders, cuffed denim trousers, sturdy black lace-up combat boots with thick soles. Seating surface: a rough-textured light grey concrete block or ledge, visible cracks and rough surface texture. Rendering style: entirely rendered as a fine-art graphite pencil sketch, dense detailed crosshatching and shading throughout the figure, clothing, and concrete block, fully monochrome grey-toned pencil illustration with no color anywhere on the figure or ledge. Background: a plain warm beige-grey textured paper background, with one large bold solid orange circle centered directly behind the subject's head and upper body, acting as a graphic halo, the circle rendered as a flat solid bright orange color with no shading or gradient, clean crisp circular edge. Color treatment: the entire illustration is monochrome pencil-grey except for the single solid orange circle, which is the only color element in the composition. Style: fine-art editorial pencil illustration, detailed realistic shading, graphic poster-art background element. Mood: contemplative, stylish, artistic, calm. Negative: no readable text, no logos, no watermark, no color anywhere except the orange circle, no direct eye contact with camera, no smiling expression, no gradient or shaded texture within the orange circle, no photorealistic rendering — must remain pencil-sketch style throughout.
