Hand – drawn illustration style, colored pencils outline a black – blue butterfly with black wings lining clear blue spots, elegant wavy edges, and slender antennae. The butterfly is semi – flying with wings one high and one low as if preparing to stop; the background is pure light gray watercolor for simplicity and shape highlighting. Soft side light makes blue spots clearer and black wings have shadow layers, with faint paper texture and breathability – enhancing white space. Mysterious and flexible black – blue contrast; details depict wing wavy edges and color transition, fully showing elegant posture.
