Envision a tall skyscraper emerging from a vibrant setting that marries the surreal artistry of Moebius with the architecture of Saudi Arabia, a scene vividly captured in a grand visual inspired by Jean Giraud. The skyscraper’s façade is adorned with bold, colorful advertisements, including a prominent red billboard and an expansive LED screen, branding it not just an architectural feat but a beacon of urban advertisement. The surroundings are a fantastic blend of natural and urban elements: a red river neatly slicing through the cityscape, a lush green grassland beside a serene blue water pool, and green mountains looming in the backdrop under a vast, turquoise sky. This amalgamation of teal, orange, and turquoise hues, combined with the dynamic forms of desert landscapes, skyscrapers, and reflective city lights, showcases a retro-futuristic vision. This detailed illustration adheres to the MidJourney –sref style guide, perfectly merging realistic touches with imaginative artistry that brings the desert city to life while capturing the spirit of both Moebius and Giraud.
