Create an ethereal, high-fidelity digital artwork capturing the essence of Blue

$Create an ethereal, high-fidelity digital artwork capturing the essence of Blue Hour, featuring a distant, solitary cat, optimized for a smartphone wallpaper (aspect ratio 9:20, resolution 1080x2400 pixels). Use Adobe Photoshop CC 2023 with custom Python scripts for procedural generation. Sky composition (70% of image height): Implement a physically-based sky model using Rayleigh and Mie scattering algorithms. Color gradient: Deep indigo (HSL: 240°, 80%, 15%) at horizon, transitioning to rich cerulean (HSL: 200°, 75%, 30%) at center, fading to steel blue (HSL: 210°, 40%, 60%) at top. Add 150-200 stars with Gaussian distribution, sizes ranging 1-3px, brightness 50-80% opacity. Celestial body (positioned at top-right third intersection): Rising crescent moon, 5% of image width, using accurate lunar phase model. Color: Cool white (HSL: 220°, 10%, 95%) with subtle blue rim lighting. Implement accurate lunar limb darkening effect. Foreground (lower 30% of image): Minimalist landscape silhouette using Perlin noise algorithm for natural contours. Color gradient: Deep blue-black (HSL: 240°, 70%, 5%) at base, transitioning to (HSL: 240°, 60%, 10%) at horizon. Add subtle fractals (0.5% opacity) for texture, simulating distant foliage or structures. Cat placement: Position cat silhouette at 2% of image height, placed 1/5 of the way up from the bottom, 1/3 from the left edge. Use bezier curves for smooth, natural feline contours. Apply 50% feathering (2px radius) to silhouette edges for softer integration. Atmospheric effects: Implement volumetric lighting using ray marching technique, emanating from moon position. Add subtle airglow effect near horizon (HSL: 160°, 40%, 20%, opacity 10%). Simulate light pollution with a soft radial gradient (HSL: 180°, 20%, 15%, opacity 5%) at horizon. Clouds: Generate 3-5 cirrus clouds using Fractal Brownian Motion algorithm. Color: Slight purple tinge (HSL: 270°, 30%, 70%) on edges, blending to sky color. Opacity ranging from 20% to 40$
