Architecture poster comic city cute

Create a cute retro cartoon cityscape of , using an innocent children's picture book style, with extremely simplified architecture, using thick geometric shapes, exaggerated proportions, and rough black outlines. Use a vertical poster composition, with a bright cyan-blue halftone sky background and a worn beige paper border. Make the clear visual center: a tall red-and-white checkered tower, with a smiling kawaii face, rosy cheeks, simple black eyes, and a small open mouth drawn on the observation deck. In the upper left, add eye-catching slanted comic lettering, writing in red-orange with black outlines, and below it, label the Japanese text 「東京」 in thick yellow font with black outlines. Include 2 huge cream-colored round clouds, one on each side. Around the tower, surround it with a simplified skyline made of blue, pink, yellow, and orange rectangular buildings. Include 5 clearly visible signs: a red vertical sign that says 「カラオケ」, a pink vertical sign that says 「原宿」, a yellow horizontal sign that says "SHIBUYA", a red vertical sign that says 「秋葉原」, and a billboard showing a portrait of a cute character with pink hair. Next to the SHIBUYA sign, additionally add a billboard with a cute white cat face. The foreground shows a row of rounded green trees, a blue river or canal with small white ripples, and a cream-and-green cartoon train entering from a curved track in the lower right corner, with the train also having a smiling kawaii face and rosy cheeks. Apply a retro comic print texture with visible halftone dots, slightly rough ink edges, saturated colors, and playful proportions, and do not include any realistic elements.
