Serene Night Sky Filled Deep

Create an illustration of a serene night sky filled with deep indigo and violet hues. Add soft, swirling clouds interspersed with sparkling stars in varying sizes. Replace the original cityscape with whimsical, fairy-tale-like buildings featuring unique, abstract spires and domes, illuminated by gentle, warm light. Incorporate a large, crescent moon with a slightly different shape, casting a shimmering glow over the landscape. Ensure the background maintains a mystical atmosphere by including hints of distant mountains and more twinkling stars scattered throughout the scene.
