圆珠笔

Redraw this pet entirely as a ballpoint pen drawing: dense blue biro hatching built up stroke by stroke, tone made only from overlapping lines with white paper left showing between them, loose scribbled passages at the edges of the drawing, and the slightly uneven ink of a cheap pen. This must read as pen strokes, never as a photograph and never as a smooth gradient. Keep this exact pet completely recognizable: the same pose, the same body proportions, its unique markings expressed as denser and sparser hatching, the same expression. Place the pet on a plain solid white background, the whole pet inside the frame, with a clearly defined silhouette. No text, no watermark, no signature, no border.
