Social-Proof Testimonial Ad — Online Course

A 1080x1350 px portrait-format social-proof testimonial ad for a fictional online course platform called LearnArc. Warm off-white background with a subtle linen texture. Upper half: a rounded square photograph showing a person (30s, professional casual, smiling warmly, East Asian appearance, no identifiable real person) seated at a bright home office desk with a laptop open, photographed with a 50mm lens at f/2.0 with soft window light. Below the photo: a row of five filled gold star glyphs. Pull-quote in large italic serif: "I landed my first UX role six weeks after finishing the course." Attribution line: "— Marcus T., Product Designer, Singapore" in small light grey sans. Center divider: a thin coral rule line. Lower section: "Join 40,000+ Career-Changers" in bold charcoal, then a brief 2-line benefit statement: "Certificate-backed courses. Taught by practitioners. Mentor support included." Bottom CTA: coral filled button reading "Browse Courses". The brand name LearnArc appears subtly in the upper-right corner in a thin sans.
