Keep the same perspective, window placement, and architectural geometry.\n\nKey edits:\n1) Building facade color: Change the main facade (currently blue) to a {argument name="facade color" default="warm, rich yellow painted plaster"}, realistic texture, slightly weathered, European old-town vibe.\n2) Window couple emphasis: Make the couple in the open window appear closer and more prominent (a subtle zoom/crop or optical framing adjustment that brings them forward), while still keeping the window in the same location on the building.\n3) Couple mood & props: The couple is happy and smiling, looking at each other with warm, joyful expressions. Each holds a wine glass (clear stemware) with red or white wine. Natural hand grip, correct reflections and refraction in glass.\n4) Flowers: Add tasteful flowers around the window area (e.g., a small window box or pots with blooming flowers such as {argument name="flower type" default="geraniums"}), and optionally subtle greenery climbing or placed nearby—must look natural and consistent with the architecture.\n\nLighting & realism:\n- Preserve the original time-of-day feel and ambient light; keep it realistic and soft.\n- Ensure natural skin tones and fabric textures; no plastic smoothing.\n- Maintain realist
