Retro Kawaii Tokyo Cartoon Poster

A cute retro cartoon cityscape poster of [Tokyo], illustrated in a naive children's picture-book style with ultra-simplified architecture, chunky geometric shapes, exaggerated proportions, and bold thick black outlines. Vertical poster composition with a worn beige paper border. In the center, [Tokyo Tower] stands as the main focus: a red-and-white lattice tower with a smiling kawaii face on its observation deck, rosy cheeks, simple dot eyes, and a small open mouth. At the upper left, large tilted comic lettering reads "[TOKYO]" in red-orange with black outlines, with chunky yellow Japanese text reading 「東京」 directly beneath it. The bright cyan-blue sky features vintage halftone dot textures and exactly two large rounded cream clouds, one on each side. The surrounding skyline features colorful blocky rectangular buildings in blues, pinks, yellows, and oranges, displaying five visible signs: a red vertical sign 「カラオケ」, a pink vertical sign 「原宿」, a yellow horizontal sign "SHIBUYA", a red vertical sign 「秋葉原」, and an illustrated billboard featuring a pink-haired anime character, alongside another billboard showing a cute white cat face beside the SHIBUYA sign. Foreground includes rounded green trees, a vibrant blue river with stylized white ripples, and a cream-and-green cartoon commuter train on curved tracks entering from the bottom right, sporting a happy smiling face with rosy cheeks. Vintage comic print texture, visible screen tone halftones, slightly rough inking, and vibrant saturated colors.
