Realistic image in the style of retro advertising of the 80s, with a slight blur and haze. Use natural lighting throughout the scene. A 350 ml glass with a minimalist design, without ribs or patterns, containing cold coffee of a dense black color with airy creamy foam on top. The short glass is placed against a sky background with clouds. The clouds should envelop the glass, partially covering it from both the front and the back. Specifically, the clouds in the foreground should obscure the bottom half of the glass, while the top half remains visible above the clouds
