紫色蝙蝠抓著空白飄帶飛來

A single broad-winged bat flies straight toward the viewer through the middle of a square 1:1 frame, its body upright at mid height and each wing stretched out to reach the left and right thirds. Its feet hold the two upper ends of a short rectangular ribbon banner, one end in each foot, and the banner hangs below the body in a gentle shallow curve. The banner plate is flat, smooth and even, kept wide and readable as a label surface for later typesetting. The bat has two perked ears, round forward-looking eyes and a small friendly grin. The whole bat-and-banner group sits entirely inside the frame, with clear empty transparent space on every side and nothing touching or cropped by an edge. Style: a flat storybook illustration made of smooth filled shapes with crisp clean edges. The palette is limited to deep plum-purple, warm charcoal and one muted pumpkin-orange accent, with a matte, print-clean finish and no texture, gradient or outline work. Colour sits in even flat fills, with a single darker tone per shape for simple two-step shading, and the light stays soft and directionless. The ribbon is plain, with clean swallow-cut ends and completely blank: no writing, lettering, symbol or decoration anywhere on it, and the bat wears no collar, tag or marking that could read as text. There is no ground and no cast or contact shadow, because any shadow pass is supplied separately. The entire subject is isolated on a fully transparent background, a real alpha channel that reads alpha = 0 at the outer edges, not white, not a colored field, and no checkerboard pattern anywhere.
