Create a highly detailed, hand-drawn 2D cartoon character illustration in a stylish, edgy, modern animated graphic novel aesthetic. Character: A quirky young man with an oversized head, slim body, slightly messy spiky hair, thick oversized black glasses, small black ear studs, and a confident, slightly unimpressed expression. Exaggerated facial features with expressive eyes, a small nose, and a subtle smirk. Pose: Waist-up portrait, body turned slightly sideways, head tilted upward, eyes looking off to the side, relaxed and casual posture. Outfit: Oversized black streetwear T-shirt with bold orange graphic lettering, natural fabric folds, and subtle shading. Art Style: Clean bold black ink outlines, exaggerated cartoon proportions, smooth cel shading, warm skin tones, crisp highlights, subtle textured brushwork, polished hand-drawn animation aesthetic. Background: Solid vibrant mustard yellow, minimal and uncluttered, with generous negative space around the character. Composition: Vertical 9:16 poster, character positioned in the center, slightly below the middle, head and upper torso fully visible. Quality: High-resolution digital illustration, professional character design, expressive personality, consistent linework, cinematic lighting. No watermark, no extra objects, no border, no photorealism.
