At the middle of the Watercolor Style image, "HAPPY BIRTHDAY DAD"

At the bottom of the image, "Have your cake and sleigh it, Dad!"

Paint in soft, cute watercolor washes with delicate gradients, subtle pigment blooms, and natural paper texture—airy, cozy, and festive.

Compose a three-panel spread:

- Center panel (front cover): Let the headline be the hero. Playful hand-lettered watercolor "HAPPY BIRTHDAY DAD" in candy-cane reds and holly greens, tiny heart accents tucked into letters. Surround with a layered birthday cake iced in vanilla, candy-cane striped candles, a tiny Santa hat, sprigs of holly, twinkly fairy lights, soft snowflake speckles, floating pink-red hearts, and a couple of wrapped presents. Keep everything whimsical and cute.

- Inside left panel (handwritten or typed, legible, friendly brush lettering), set the note on its own lines:

Dear Dad,

Happy Birthday. Thank you for everything you do for me. For example, getting the Christmas tree and watching Boston Blue. Hope you have a wonderful day.

Love you a lot.

Love, Sis

Add gentle doodles: a mini evergreen sprig, a tiny heart, faint snowflake corners, and a warm cocoa mug.

- Inside right panel: festive decorations only—pastel balloons drifting around a watercolor Christmas tree decorated with heart ornaments; wrapped presents at the base; playful confetti; and a delicate snowflake border framing the panel.

Palette: blush pinks, holly greens, candy-cane reds, icing cream, twinkle gold, and icy blues. Lighting: soft winter glow; crisp, readable text; cute mood throughout.

Generated with these themes: Front cover: keep the “HAPPY BIRTHDAY DAD” with hearts, cake, and Christmas touches. Inside left: write or type your updated note: Code Dear Dad, Happy Birthday. Thank you for everything you do for me. For example, getting the Christmas tree and watching Boston Blue. Hope you have a wonderful day. Love you a lot. Love, Sis Inside right: keep the festive decorations (balloons, Christmas tree, confetti, presents, snowflake border)., and .
