Calm Heron Sunrise Lake

Create a serene impressionist oil-painting landscape of a misty lake at {argument name="time of day" default="sunrise"}, expressing {argument name="mood" default="calmness and quiet reflection"}. Use a wide horizontal canvas, about 16:9. The scene shows exactly 1 tall blue-gray heron standing in shallow water slightly right of center, facing left, with long legs, an orange beak, and a clear dark reflection in the still water. Add exactly 1 prominent flowering willow tree on the far right bank, with drooping branches and pale pink blossoms, plus soft distant tree silhouettes along the horizon. The lake surface should be glassy with gentle ripples, pastel reflections of the sky, and a warm sun low near the center of the horizon. Include exactly 21 water-lily flowers: 19 open blossoms and 2 closed buds, distributed as 4 open blossoms and 2 buds in the lower-left foreground, 3 open blossoms near the center reeds, 5 small open blossoms along the mid-right waterline, and 7 open blossoms among the large lily pads in the lower-right foreground. Surround them with dark green lily pads and tall reeds around the heron. Use a dreamy {argument name="color palette" default="soft peach, lavender, rose pink, misty blue, teal green, and warm gold"} palette, visible painterly brushstrokes, soft atmospheric haze, romantic natural lighting, delicate reflections, no text, no people, no buildings, no harsh contrast.
