Prompt: sci-fi movie still of an alien gunslinger wearing a trench coat and hat, with a insect-like face, aiming a futuristic rifle, riding a large alien monster with tentacles at high speed, out in a flat and empty desert, hard sunlight, action shot with a cinematic angle, shot on 35mm vistavision film --ar 8:5 --style raw

The face didn’t work out so well, but I like the rest of the image :)
