Create a painting of a futuristic, floating cityscape where transport is powered by giant, colorful hot air balloons roaming the sky.
Revised Prompt
Imagine a vision of the future where cityscapes float in the sky held aloft by an invisible force. Architectures of gleaming metal and luminescent glass with green rooftops and multitudinous vegetations punctuating the skylines. Dominating the azure firmament are massive, vibrant hot air balloons, glowing like jewels in a field of cobalt. These balloons, equipped with all manner of technological marvels, serve as the main mode of transport for the city's inhabitants, who travel to and from their destinations in these chariots of the air, their radiant trails painting vivid streaks across the sky.
