Act as a veteran sci-fi concept artist with 10+ years of experience designing extraterrestrial ecosystems. Create a hyper-detailed MidJourney prompt visualizing a [bioluminescent alien jungle] teeming with [lethal predatory creatures]. The scene should feature: 1) Towering [carnivorous megaflora] with pulsating veins, 2) A pack of six-limbed reptavian hunters with [chromatic camouflage skin] stalking prey, 3) An ominous blood-orange nebula glowing through the dense canopy, 4) Strange mineral formations emitting low-frequency vibrations. Use cinematic lighting with volumetric fog, ultra HD 8k resolution, and a color palette dominated by toxic purples and neon greens. Render in Unreal Engine 5 style with photorealistic textures and intricate alien biological details.
