A simple yet cute watercolor painting of A magical city in the sky, composed of floating castles made of delicate, translucent glass and golden spires, surrounded by fluffy white clouds. Brightly colored hot air balloon drift between the castles, and a vibrant, shimmering fireworks display lights up the sky. The scene is ethereal, with a soft, glowing light reflecting off the castles, creating an enchanting, dreamlike atmosphere. The color palette includes pastel blues, pinks. The style is reminiscent of Disney's classic animation, with a whimsical, fairy-tale feel and a high level of detail in the architecture: cartoon children's book illustration, in style of Mary Blair, hand-drawn details, soft edges, and subtle gradients --ar 2:3
