To me, a classic sign of the Holidays is the Cardinal. The stark contrast between his bright plumage and the white of snow helps him to stand out as a sure symbol of the season.
Watercoloured Cardinal with gold embossed greeting and shimmery snowflake accents. Barely visible around him is a frosted blue aura, this helps him to stand out against the background and additionally lend to the illusion of winter.
