Technical sketchbook plate on warm ivory paper: delicate graphite pencil and fine ink line with ruled perspective guidelines, neat parallel hatching and soft tonal pencil shading, translucent geometric colour-wash swatches overlaying sections of the drawing and letting the pencil work show through, a faint survey grid, generous empty margins and no text or lettering. Headshot framing: in a workshop, a fictional adult Chinese-American founder, a woman in her forties with a short black pixie cut in a canvas work apron over a plain tee, head and shoulders, standing at a workbench holding a small unlabelled hardware prototype up to the light and inspecting it with a satisfied half-smile, a pegboard of hand tools drawn behind her.
Light: soft tonal pencil shading across her face and the prototype, ruled perspective lines running into the pegboard, a few translucent teal and ochre colour-wash swatches over the apron and the workbench, a faint survey grid; graphite on warm ivory with teal and ochre washes; precise, hands-on, sketchbook-like.
Square 1:1 frame, centred composition with breathing room on all sides. A fictional adult, fully clothed in modern business-casual clothes, with natural, realistic features and a dignified, confident expression; a plain contemporary setting with no readable text, logos, slides, signs or name badges.
