A monochromatic pencil sketch of a guinea pig using 4B pencil and strong strokes. The drawing features a realistic representation of the guinea pig nibbling on a piece of food, positioned slightly off-center in the composition. The guinea pig is gazing directly at the viewer with an expression of curiosity. Its eyes are rendered with a detailed, expressive gaze, and its fur is subtly highlighted with textured strokes. Every stroke is unique and bold, with fading and fewer strokes to outline the body, creating a sense of softness and focus on its adorable expression.
