cinematic, ultra realistic, ultra detailed, Design a digital painting movie poster for 'CivitAI Galaxy' a space horror movie set on an alien planet. The poster features an upper body shot of a blonde wavy short haired female astronaut in a sci- fi space suit without helmet, holding a sci- fi rifle, looking at viewer, frozen in terror as an intimidating otherworldly alien monstrosity looming in shadow behind her. The focus is on the heroine, whose space suit wide open at neck reveals her clevage covered a black lace bra. The alien creature is barely visible with its disproportionately huge and elongated T- REX like head with multiple eye sockets but no eye ball, horns and grotesque tentacles growing around its neck, and multiple sets of elongated dinosaur- like arms showing distorted images of Lovecraftian cosmic horror. Its mouth is open wide, showing multiple rows of shark- like teeth. The background is a dark outer space with ominous colors, a futuristic spaceship floating, indicating there's no help for the heroine. The title 'CivitAI Galaxy' is in black texts with light blue frame below the monster. The color scheme is entirely light blue and dark blue, with sharp contrasts between light and dark enhancing the film's tense and horrifying atmosphere of hopelessness
