A cozy anime-style illustration of a young girl in her early 20s blowing candles on a birthday cake, soft pastel colors, warm lighting, Studio Ghibli-inspired aesthetic. Sitting on a sunlit living room floor wearing casual outfits (pastel sweaters and jeans). Background features a cozy apartment with plants, bookshelves, and a large window showing cherry blossom trees outside. Dynamic poses, gentle smiles, floating dust particles in sunlight, vibrant but soothing color palette, detailed textures in fabrics, 4K resolution, ultra-detailed, Studio Trigger-inspired linework with Makoto Shinkai-style atmospheric effects.
