Create a finished portrait birthday invitation, aspect ratio 3:4, with a bright children’s party cartoon aesthetic. Use a saturated bubblegum-pink background (#FF4FA3), with a full-bleed festive scene and no extra lettering, numbers, logos, or text beyond the four exact copy lines below. Keep the composition centered and preserve this top-to-bottom structure and relative spacing: a dominant headline near the top, spanning almost the full width; a smaller single-line date beneath it in a narrower centered block; a large central graphic zone; then two separate, centered detail lines near the bottom, with comfortable space between them and the lower edge. Maintain clear separation between every text block and the artwork. Set the headline exactly as: “MIA’S 7TH BIRTHDAY”. Make it the largest text, in chunky, rounded, plump 3D foil-balloon letterforms. Give the individual letters cycling bright saturated red, orange, yellow, green, blue, and purple candy colors, with taut reflective metallic skins, rounded inflated contours, thick black cartoon outlines, tiny tied balloon knots, bright specular gleams, and soft cast shadows. Keep the lettering crisp and immediately legible. Set the date on one centered line exactly as: “SATURDAY, NOVEMBER 14 · 2 PM”. Use smaller bold rounded cartoon lettering with high-contrast white fill, a clean dark outline, and generous tracking sufficient to read at invitation size. In the central graphic zone, stage a joyful foil-balloon burst: a large shiny yellow number-shaped balloon with no printed text, surrounded by oversized pink, sky-blue (#21B9F2), and lime-green (#7BD83B) balloons. Add curling ribbons, colorful confetti, cartoon starbursts, and a few hearts, radiating outward while leaving the text areas unobstructed. Keep balloon contours soft and rounded, with bright highlights and dimensional shadows. Set the first bottom detail exactly as: “SUNNY PARK PAVILION”. Below it, set exactly: “RSVP BY NOVEMBER 7”. Use smaller, bold white rounded lettering with dark outlines, centered in separate compact blocks; keep both lines easy for parents to scan. Use vivid flat cartoon colors, thick outlines, glossy reflections, lively confetti, and strong text-to-background contrast throughout.
