A detailed sketch of huge machinery with a metal casing, featuring a drill bit, grab bucket, track, and cable details. The scene includes close-up views of a hydraulic rod, robotic arm, boom, and crane. Drawn in a pen and sketchbook, the sketch incorporates gray, brown, and dark green watercolor and ink paintings with appropriate sketching pen touches and texture. The light gray colored earth contrasts with the solid, vibrant background. Behind the building, AIGC SKETCH is graffitied in bold letters and sprayed with a thick coat of black paint.
