At the top of the Illustration Style image, hand-letter "Happy Birthday John" in an elegant warm-cream brush script with tiny diamond-sparkle accents, gently arched to echo the rainbow.

Hand-drawn, romantic illustration with fine linework, textured brush strokes, balanced composition, and a warm, expressive color palette. Scene: A whimsical vintage ocean liner inspired by the Titanic glides through a calm twilight sea. At the bow, two dachshunds lean close, tails curled into a heart, one wearing a delicate diamond collar while the other offers a tiny diamond-shaped charm; soft golden rim light on their fur. Penguins bustle adorably as the ship’s cheerful crew, their natural tuxedos popping against the warm hues: one penguin releases rainbow-colored confetti that drifts like stardust, another carries a little lantern casting a honeyed glow, and a third steadies a string of diamond-shaped fairy lights along the railing. A full luminous rainbow spans the sky and shimmers in the water below; the ship’s smokestacks exhale faint heart-shaped clouds. The sea glitters with painterly highlights, forming a subtle heart in the wake. Diamonds twinkle as starry facets in the sky and along the deck trim. Color palette: blush pinks, peach, coral, apricot, teal, deep indigo, and champagne gold accents. Paper grain visible, delicate ink hatching, watercolor washes, and a gentle vignette that draws the eye to the dachshunds at the bow.

Optional subtle caption: at the bottom center on a small ribbon banner, hand-letter in a playful script, "You're my fur-st class love." Keep the caption small so the large, romantic image remains the focus.
