Y2K bubbly inflated letters — extremely round pillow-soft letter forms completely inflated like over-pressurized balloons. Pastel pink-to-lavender gradient across the glossy candy surface. Strong white specular highlight on the top of each inflated letter. Extremely smooth and soft surface. Sweet 2000s Y2K party aesthetic. Maximum bubbly inflation quality. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style governs the over-inflated pillow form, the glossy candy surface and the speculars. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as extremely round over-inflated pillow letters with an ultra-smooth glossy candy surface and a strong white top specular. COLOR PRIORITY: keep the font's own colors if specified; otherwise a pastel pink-to-lavender gradient. Portrait 3:4. Render the exact text “落叶” as the sole oversized hero composition, centered with generous breathing room. The two characters are maximally over-inflated, pillow-soft and swollen outward like glossy candy balloons, their strokes retaining clear, legible character structure while every edge bulges into smooth rounded volume. A warm autumnal gradient rolls across the ultra-smooth surface: peach pink at the upper curves, lilac through the center, and soft amber-gold along the lower rounded forms. Strong white oval specular highlights sit near the top of each inflated character, with gentle candy-colored inner glow and faint lavender reflections defining the seams and deep enclosed spaces. Set against a hazy pastel sky gradient of blush pink, powder blue, and pale lavender. Around the text, a sparse drift of small glossy autumn leaves floats downward: maple and ginkgo silhouettes in translucent coral, buttery yellow, and pink plastic, each with tiny bright highlights. A few silver star stickers and soft white sparkle dots add a playful Y2K diary-cover touch. Ground the characters with a feather-soft violet shadow beneath them. Sweet, nostalgic autumn Y2K mood, toy-plastic gloss, maximum roundness, clean polished negative space.
