Edit this exact photo. Keep the camera position, framing, lens, light and every object exactly as they are: the white L-shaped sofa in the same place and angle, the round wooden coffee table, the rug, the green armchair with the plaid, the dining table by the window, the kitchen island with stools, the staircase, lamps, plants. Change nothing in the room.
Add only one thing: in the open floor space between the coffee table and the kitchen island, a sleek modern portal hovering just above the floor, about two meters tall: a razor-thin oval ring of white-cyan light, inside it a vertical membrane of rippling liquid glass, and through it a deep turquoise underwater world with sunbeams and glowing jellyfish. Soft caustic water-light reflections on the nearby floor. Premium, minimal, photoreal VFX.
