Design a dreamlike scene of a castle on a cloud cushion

Imagine a magnificent castle perched atop a vast, ethereal cloud that stretches across a soft, pastel-hued sky. The castle is constructed from gleaming white stone, with tall, slender spires that pierce the heavens, adorned with silver and gold accents that shimmer in the sunlight. Wisps of mist float gently around the base, where the clouds form a soft foundation, blending seamlessly with the sky below. The castle towers stand tall, their turrets topped with delicate flags fluttering in the soft breeze. The windows glisten like crystal, catching and refracting light in a kaleidoscope of colours. Ivy-like vines of golden hue wrap themselves around the walls, glowing faintly in the ambient light. Surrounding the castle, the clouds are thick and plush, like billowing cotton candy. Patches of vibrant wildflowers and small pools of crystalline water break through the surface of the clouds, creating an otherworldly floating garden. Above, the sky shifts between shades of lavender, peach, and rose, with a glowing sun that hovers just above the horizon, casting long, golden rays across the scene. The whole atmosphere feels serene and enchanted, as if time stands still in this dreamy, floating paradise.
