December Moon Icon Collection

Create an icon collection that represents the [moon], symbols, and icons that express the mood.
They are united as a single unified theme.
The background is pure white.

Place the month name "{argument name="monthname" default="Texember"}" at the top center of the image as a minimal and balanced title. Place them symmetrically on the grid to visually integrate with the overall design.

Colors should be rendered in a colorful yet calm 3D style using season-appropriate textures and atmospheric lighting. This reflects the essence of Japan's {argument name="月名" default="Tsukatsu"}.

Maintain consistent proportions, materials, and visual language across all icons and titles.
