At the top of the Illustration Style image, in whimsical, swirling font: "Happy Sweet 16, Felicity!"

**Image Description:**

In the foreground, a charmingly illustrated Tardis, the iconic blue police box from Doctor Who, stands slightly ajar with a soft, warm glow emanating from inside, inviting viewers into its mysterious depths. Around the Tardis, a vibrant cosmos bursts with swirling galaxies and twinkling stars, rendered in a warm, expressive color palette of deep blues, purples, and sparkling whites.

Floating gently in this interstellar backdrop are cheerful elements of a 16th birthday celebration: balloons shaped like planets, confetti stars, and a whimsical banner trailing from the Tardis door that reads: "Time to Celebrate!" in a playful font. The Tardis itself is lovingly detailed with hand-drawn fine lines and textured brush strokes, emphasizing its beloved, slightly vintage look.

In the corner, an adorable cartoon version of the Doctor’s iconic sonic screwdriver peeks out, as if to say it's ready for a day of fun and adventure. The entire scene is a balanced composition that captures both the wonder of Doctor Who and the joy of turning sixteen, all in a delightfully cute and heartwarming style.
