- What worked
- Both final images accurately displayed 'Warm Christmas' and 'Haru' in exactly two lines once each, with no extra periods. Confirmed the snowy house with a red sled at night, green/red/ivory color scheme, opaque gouache brushstrokes, and borderless vertical orientation. Verified the connection of the sled seat, supports, runners, and rope. In the final two images, the text did not invade the lower 15% area. Generated at 1122x1402, which is an aspect ratio error of about 0.04% compared to 4:5 (due to rounding of the generation size).
- What did not work
- None
- How to improve
- Keep the greeting field as two lines like the example. The revision that actually worked in the test was placing the greeting body between <greeting> and </greeting> and removing the period that was automatically appended right after the greeting. Changing the prompt to position the entire two-line text higher secured the lower 15% margin, though exact coordinate adherence was not fully achieved.

Color palette: 【Colors】. Green · Red means forest green, muted red and ivory; Sky blue · White means sky blue, white and subtle violet shadows. Blank colors means Green · Red.

Set the entire greeting block, including every line and name, within a calm snow area between 60 and 75 percent down the canvas. Place the first line near 63 percent and the second line near 71 percent. The bottom edge of the last glyph must stay above 80 percent of the canvas height. Fit all lettering inside this area; leave the bottom 15 percent free of letters. Use large legible hand-painted lettering. Do not append punctuation that is absent from the greeting. Keep snowflakes and objects off letters. Create one coherent scene with a strong focal subject, layered landscape and intentional space around lettering. Fill the canvas edge to edge, no frame, photographed card, mockup, collage or promotional title.

Before returning, compare every letter with the greeting and check the palette, requested aspect ratio, anatomy and sled geometry. Output only the single finished image.
