Hand – drawn illustration style, colored pencils carefully depict a blue – winged butterfly with sapphire blue main color, dark brown and tiny white edge spots, and slightly incomplete wing edges for more realism. The butterfly spreads wings flat and lies on light brown mottled ground as if just stopped. The background is light brown watercolor to restore rough texture; soft uniform upper light makes blue wings stand out on brown, with natural paper texture and concise white space. Simple and eye – catching blue – brown contrast; details depict wing incomplete texture and ground mottles, fully showing real state and texture of natural creatures.
