Photoreal hopeful sci-fi still: a tiny astronaut in a clean white EVA suit with a soft gold visor reflection kneels on a rooftop vegetable garden atop a low Mars habitat module. Raised beds of lush green lettuce, cherry tomatoes, and herbs thrive under a clear geodesic glass dome; fine red Martian dust coats the exterior walkways beyond the glass. The astronaut holds a small watering can, focused on a tomato plant. Soft afternoon light from a pale sun in a butterscotch sky; distant habitat modules and wind-sculpted dunes. Warm interior grow-lights glow faintly for contrast. Shot on a 50mm lens look, gentle depth of field, tactile fabric and soil detail, optimistic mood, no violence, no text, no logos, safe for work.
