Hình minh họa cảnh quan thành phố kỳ lạ

Prompt on Nano Banana Pro : Visualize a whimsical illustration of a cityscape, drawn in a playful, sketch-like style with pencil lines and soft watercolor fills creating a charming, storybook feel. The buildings are a mix of classic and fantastical architecture, with exaggerated features like spiraling towers and floating balconies. Amidst this illustrated backdrop, a single, ultra-realistic red balloon floats through the scene. The balloon stands out with its glossy texture and lifelike reflections, casting a realistic shadow over the illustrated buildings below. It's as if a real balloon has drifted into an imaginative, drawn world, creating a captivating contrast between the two-dimensional illustration and the three-dimensional realism of the balloon.
