Create an awe-inspiring digital image of a futuristic cityscape that highlights the advanced design and cutting-edge technology of an alien civilization. This city should be composed of towering buildings, each uniquely shaped and adorned with shimmering facades made from innovative, otherworldly materials. Dynamic lighting, with vivid hues of emerald green and deep indigo, should electrify the cityscape. Holographic streams and floating fountains emerge among lush gardens and avant-garde sculptures. The background features a smooth expanse of space, where stars and distant galaxies create a stunning contrast to the organic beauty of the city. The atmosphere should be epic, exciting, with a celestial touch, featuring soft, ambient lighting that employs HDRI for optimal realism. The image should deliver the highest level of professionalism, designed using industry-leading equipment such as 35mm, Zeiss, Hasselblad, Fujifilm, Arriflex, IMAX, and presented in resolutions up to 8k. Expect hyper-realistic renderings including lens flares, resembling a matte painting or concept art with a delicate, detailed focus on architectural elements. The artwork should meet the quality standards of CGSociety and Octane Render, achieving a supreme level of detail that is inspiring, and worthy of being featured in a premium magazine or as a high-quality wallpaper.
