Trio de Personagens em Capa de Livro Retrô

Retro children's literature book cover illustration featuring [Game Character 1], [Game Character 2], and [Game Character 3] in a mid-century naive hand-drawn style. - Composition: Centered vertical stack of three distinct tiers peeking out from behind invisible horizontal edges that match the solid dark background. The top tier shows head and hands peeking over; the middle tier shows only the head; the bottom tier shows head and hands resting on the edge. Clean horizontal occlusion cuts off the lower bodies, leaving balanced negative space between layers and on the sides. - Characters & Expressions: Retain iconic hairstyles, hair colors, eyes, collars, and signature accessories of each character. Cartoonish proportions with slightly enlarged expressive eyes; characters display distinct expressions such as sleepy, surprised, aloof, or curious. - Art Style & Medium: Gouache color blocks, textured colored pencil line work, and dry brush strokes for hair, garments, and skin. Visible rough hand-drawn textures, paper grain, and mid-20th-century print aesthetic. Warm skin tones contrast against the solid dark background.
