Technical Chemist: Blue Flask Engraving

"A highly detailed monochrome technical ink illustration of a mysterious chemist wearing a black pork pie hat, round glasses, a trimmed beard, and a long trench coat with a golden-yellow inner collar. He is holding a laboratory flask filled with glowing electric-blue liquid while wearing black tactical gloves. The portrait is shown in a dramatic three-quarter view with an intense downward gaze. The artwork features intricate cross-hatching, fine pen-and-ink engraving, architectural line work, blueprint circles, geometric construction marks, technical diagrams, abstract scientific symbols, splattered ink textures, and sketchbook imperfections. Minimalist white background with floating engineering annotations and precision drafting elements surrounding the subject. Selective color accents limited to vibrant cyan liquid and muted golden fabric, with the rest rendered in black and white. Ultra-detailed line art, engraved illustration, technical sketch aesthetic, modern poster design, high contrast, museum-quality composition, crisp vector-like ink strokes, negative space, editorial graphic design, premium screen-print style, 8k resolution."
