Realistic Cartoon Character Portrait

Create an original stylized photoreal character image for Northstar AI featuring an original bicycle mechanic rendered between editorial photography and graphic cartoon. Objective: Blend realistic materials with deliberately simplified facial and shape language. Composition: Waist-up workshop portrait, tools as quiet background shapes and one crisp rim light. Lighting and material treatment: Controlled editorial lighting, coherent materials and a restrained palette suited to the stated medium. Typography: do not include any words, letters, numbers or signatures. Use a deliberate hierarchy, clean edges, realistic shadows where appropriate, and enough negative space for editorial reuse. Output a polished 4:5 vertical composition unless the user specifies another ratio. Required constraints: No uncanny skin, celebrity likeness, studio-brand style imitation, distorted hands or fake logos. Do not add watermarks, fake certifications, unreadable filler text, duplicated objects, distorted anatomy, or unrequested logos. Preserve any uploaded product, person, or interface as the identity reference rather than redesigning it.
