Prompt
[Happy Valentine's Day letter] written in flowing [hand-lettered script] fills the left two-thirds of a 3:2 frame, with the central calligraphy block positioned slightly left-of-center and generous negative space in the upper right for balance. A polished [fountain pen] rests in the center-right foreground with its nib angled toward the script and occupying roughly one quarter of the frame, casting a soft shadow across the paper. The scene is photographed as close macro-photography with a low-angle viewpoint that keeps the foreground nib sharply resolved while the background and edges fall into creamy bokeh. Soft, warm front-side light creates gentle highlights on metallic and inked surfaces while moderating midtone contrast for a romantic feel. Paper texture reads subtly near the lettering while reflective accents on the pen and tiny ink-splatter highlights catch the light. Overall color leans warm with deep slate shadows, muted beige paper, and small burgundy heart accents for contrast. Maintain a 3:2 aspect ratio, tight crop that preserves the pen in the right third and the main lettering block in the left two-thirds for poster-cover use.
