generate a highly detailed and realistic image of a wall with a mixture of warm beige and soft gray concrete texture, featuring slight imperfections and cracks, with a subtle sheen to suggest a recent coat of paint, under soft and diffused natural lighting that casts no harsh shadows, with a slight gradient of darker tones towards the bottom where the wall meets the floor, and a faint reflection of a window on the adjacent wall, with the overall style being photography-like and the colors being muted and earthy.
