Prompt:
Create a 1980s sci-fi book cover scene with a muscular man and an athletic woman in a futuristic setting. The man appears to be in his 30s, with a square jaw, intense blue eyes, and slicked-back blond hair. He's crouching on one knee, wearing a sleeveless white shirt with yellow trim and a symbol on the chest, gray pants, and black boots. He's gripping a metallic structure with his left hand and holding a futuristic blue gun with his right. The woman looks to be in her 20s, with golden-brown hair styled into a short, wavy bob, and confident green eyes. She's wearing a red two-piece outfit consisting of a midriff-baring top with a belt and a symbol matching the man's, and high-waisted shorts, paired with red knee-high boots. they are in a mystical greenhouse interior with a large glass dome ceiling that filters soft, diffuse light, casting a serene greenish hue over the scene. The focal point is a centrally placed, transparent spherical terrarium resting on a circular black pedestal. The terrarium encapsulates a miniature fantastical forest with a prominent, gnarled tree with twisting roots and branches, topped by an oversized, translucent mushroom-like canopy. The forest ground within the sphere is lush with green moss and tiny pinkish-red toadstools.
Surrounding the terrarium, the greenhouse is filled with an array of otherworldly flora, including tall, slender fungi resembling floor lamps with smooth umbrella-like caps and a range of bushy, moss-covered outcroppings. The floor, a mix of earthy cobblestone and natural ground, leads to the terrarium via a winding pathway. In the background, multiple tiers of dark metallic shelves hold potted plants and mosses, complementing the eerie, botanical ambiance. Faint fog creeps around the base of the greenhouse structures, enhancing the sense of an enchanted, secluded sanctuary.
