Prompt
A single person stands as the primary subject slightly left of center in a 3:2 frame with a giant circular red UNDO button occupying the lower-right third of the composition, the button face bold with white uppercase "UNDO" lettering and matte plastic texture visible at arm's reach. The person is shown full-length at eye-level with a subtle low-angle suggestion, occupying roughly one-quarter of the frame height so the figure reads smaller against the oversized object and leaves generous negative space in the upper two-thirds. Cinematic mixed light sculpts the scene with a cool key from camera-right and a warm rim from camera-left, creating crisp separation and a soft falloff onto the dark slate background. Surfaces show tactile detail: woven coat fabric, skin with natural pores, and the button's brushed plastic rim with tiny specular highlights. The background is minimal and deep, filling the upper 60% of the frame with subtle gradient and no distracting elements to keep focus on the interaction. Compose and crop for a 3:2 poster-cover layout with safe space along the top and left for title typography and left-aligned copy while keeping the central action clear and readable.
