หน้าสมุดสเก็ตช์พัฒนาแนวคิดตัวละคร

An illustrator's personal character exploration sketchbook page on a pure bright white background, using the reference photo as a strict facial reference with exact facial structure preservation. The page features a spontaneous, organic, overlapping collage of scattered drawings of varying sizes and angles. Include expressive full-body sketches, detailed face close-ups, rough construction lines, loose gesture drawings, exaggerated reaction faces, chibi mini versions, three-quarter and profile angles, unfinished line-art fragments, layered redraws, crossed-out sketch attempts, handwritten technical notes, tiny arrows, and humorous marginal scribbles. The character wears relaxed modern streetwear with a creative-tech aesthetic, including [football-inspired outfits], layered hoodies, clean sneakers, subtle wrist accessories, and occasional [Arsenal-inspired] graphic details. Visual style: traditional animation development sketchbook, confident graphite pencil strokes, raw ink marks with varying line weights, light smudges, and mostly monochrome tones with selective soft accent colors, creating an authentic working concept artist's notebook feel.
