Ink-wash grand freehand style, with bold and forceful brushstrokes and lines, the texture of rice paper, calligraphic brushwork, and the artistic conception of stone rubbing. The painting takes Batman’s cape as the absolute visual subject — The cape occupies most of the frame. Using thick ink and dry brush with flying white strokes to sweep out a huge bat-wing shape, its edges extend in fragmented forms toward the four corners of the painting (expressed with scattered ink dots and flying white brushstrokes). The folds and tension of the fabric are outlined with bold lines on the cape, as if being violently tugged by the night wind. Batman’s figure is reduced to the center of the cape — his dark armor is outlined with simple thick lines, the pointed cowl is sharply defined, and his body is in a diving pose (arms outstretched, legs drawn back), forming a compositional relationship of "central core + outstretched wings" with the cape. Background: Gotham’s night sky — above Batman, a searchlight bat signal pierces through the clouds (rendered as a fan-shaped pillar of blank space), while below lie distant city lights (depicted with dense pale ink dots), and spires of Gothic buildings are subtly dotted in the cityscape with short, thick ink lines. The ink colors are dominated by thick and焦墨 (burned ink) for the main part of the cape, with pale ink for the background city, and large areas of blank space (the night sky) that accentuate the cape’s tension and dynamism. The overall atmosphere is sharp, swift, dark yet imbued with a touch of heroic pathos.
