Champ de fleurs onirique sur le toit d'un van

Create an ultra-realistic cinematic dreamy lifestyle photograph of {argument name="subject" default="a young woman"} sitting alone on the white roof of a vintage {argument name="van color" default="turquoise"} van in a vast pastel wildflower field. Use a closer low-angle portrait framing that focuses on her upper body, dangling legs, and the rooftop/side window section of the van, with the van filling the lower half of the image and a wide soft blue sky filling the upper background. She sits casually on the roof edge with both legs hanging straight down, wearing {argument name="outfit" default="a pale blue sleeveless summer dress and white sneakers"}, holding a small bouquet of mixed wildflowers in both hands on her lap, looking slightly upward with a soft natural smile and relaxed youthful mood. Her long dark hair is gently blown by the wind and the dress fabric flows softly. Tie a cluster of exactly 6 pastel balloons beside her on the left, in pale blue and white, floating from white strings attached near the van roof. Add handwritten white diary-style sketch text in the sky: exactly 4 phrases reading {argument name="main sky phrase" default="my happy place"} arched above her head, plus “bloom” on the left, “sunny day” on the right, and one small curved motion mark near the bouquet. Integrate exactly 16 white doodles around the sky and field: 4 five-point stars, 4 simple flowers, 2 smiley faces, 1 large smile curve near the lower left, 1 sparkle diamond at the bottom right, 1 small butterfly-like mark, and 3 short decorative curved strokes. Keep the doodles hand-drawn, thin, chalky white, naturally composited as if floating in the air. Lighting is bright natural daylight with soft overexposed highlights, dreamy glow, bloom effect, pastel film tones, low contrast, smooth highlight roll-off, airy clean negative space, and a color palette of turquoise, sky blue, soft white, pastel pink, pastel yellow, and warm cream. Make the image peaceful, whimsical, intimate, youthful, and carefree, with crisp realistic subject and vehicle details but soft atmospheric background.
