不安そうな若いランナーの鉛筆スケッチイラスト

A caricature of a scrawny, anxious-looking young person with a large nose, big eyes, and messy, windswept hair is depicted running. They are wearing a t-shirt and shorts, and earbuds connected to a device held in their hand. The style is a detailed pencil sketch with light cross-hatching, giving it a slightly textured, hand-drawn feel. The figure is rendered with exaggerated features typical of children's book illustrations. The color palette is muted, with the main tones being grayscale and sepia, accented by a subtle purple gradient in the upper left background, suggesting a spotlight or a stage. The lighting is dramatic, casting shadows and highlighting the contours of the character's face and body. The composition is a medium shot, capturing the full figure in motion, with a shallow depth of field that blurs the background slightly. The overall mood is one of nervous energy and mild distress, as if the character is reluctantly exercising. The art style evokes classic children's book illustrations or editorial cartoons.
