Detailed Anime Post Apocalyptic Scavenger Kids

Create a stylized anime / manga illustration of two young post apocalyptic scavenger kids sitting side by side on a cracked concrete wall in a ruined city under a bright blue sky. The scene has exactly 2 human characters and 1 small cat. The left character is a sleepy blond child with messy pale hair, half closed eyes, and a white oversized hooded poncho shaped like a strange creature skin, with black spots, circular eye like markings, and a tall cylindrical canister or launcher strapped vertically behind the head; they hold 1 long black futuristic rifle standing upright between their knees, wear dark shorts, white socks, chunky green sneakers, and knee pads. The right character is a calm gray haired child with a short bob haircut, half closed eyes, and a white skull like animal helmet with 2 large orange eye holes and little teeth along the brim; they wear a blue jacket over black layers, a gray scarf, tactical straps, a tan backpack covered in patches, olive pants with knee pads, white socks, and oversized orange boots. Place the 1 cat at the lower right, sitting beside the wall, dark charcoal gray with pointed ears, yellow eyes, and a mildly annoyed expression. The background should show a sparse ruined urban skyline with exactly 2 visible tall ruined buildings, broken wall slabs, scattered debris, small flying rubble pieces, 1 black bird silhouette, and puffy white clouds. Use clean thick black outlines, flat cel shading, pastel colors, exaggerated oversized shoes and gear, cute but gritty sci fi adventure energy, vertical portrait composition, low angle view, no photorealism, no text, no watermark. Customize the main details with {argument name="character duo" default="two young post apocalyptic scavenger kids"}, {argument name="left character hair color" default="messy pale blond"}, {argument name="right character helmet" default="white skull like animal helmet with orange eye holes"}, {argument name="weapon" default="long black futuristic rifle"}, and {argument name="setting" default="ruined city under a bright blue sky"}.
