Playful, funny cartoon with exaggerated proportions, thick black outlines, and bright saturated colors. Portrait composition, full-bleed. In a lively, candy-colored workshop, engineer Sophie (big round glasses, messy ponytail with a pencil tucked in, oversized tool belt, chunky boots) strikes an energetic pose while fine-tuning her amazing Rube-Goldberg birthday machine. The contraption bursts with whimsy: shiny gears shaped like candles, conveyor belts ferrying cupcakes, robotic arms icing a towering cake, a confetti cannon blasting rainbow confetti, a balloon inflator whooshing balloons, and a gift-wrapping arm tying a squeaky bow. Frosting splats, streamers, and sparkly motion swirls fill the air. Sophie juggles a blueprint (no words) and a wrench, grinning with determined delight. A tiny helper robot in a party hat and safety goggles offers a bolt. Background details: bunting, colorful caution stripes, doodle schematics on the walls (no text). High contrast, glossy highlights, chunky shadows; dynamic perspective and energetic poses. Only text in the image (one short line), in a small playful banner at the bottom: “Happy Birthday—Engineered by Sophie!” Do not include any other text anywhere.
