At the top of the Illustration Style image, "Happy Sweet 16, Felicity" in a playful, cosmic-themed font.

**Image Description:**

A hand-drawn illustration depicting a whimsical and enchanting scene perfect for a birthday card. The Tardis, a classic blue police box, stands majestically at the center of the image, slightly tilted as if just having landed in an otherworldly landscape. It's surrounded by a vibrant nebula filled with swirling colors of purples, pinks, and blues, with twinkling stars scattered throughout the cosmic sky.

In the foreground, floating in the space around the Tardis, are colorful balloons in shades of blue, silver, and purple, creating a festive atmosphere. Some of the balloons are tied together in the shape of the number '16', emphasizing the special milestone birthday. The background is a deep space scene, rich with sparkling stars and distant galaxies, adding to the sense of adventure and wonder.

To add a touch of humor and charm, a small alien with a party hat peeks out from behind the Tardis, waving with a friendly smile. The warm color palette and textured brush strokes create a joyful and imaginative birthday greeting, perfect for celebrating Felicity's Sweet 16 in a unique and cosmic way.
