21 birthday, and Maths equation for love and happiness Birthday Card

Description

**Prompt:**

At the top of the realistic photograph image, “Isabel, you've officially hit the age where X = wine, Y = naps, and Z = questionable decisions!”

A realistic photograph of a cluttered chalkboard in a cosy café setting, covered in colourful chalk-drawn complex math equations that comically equate love + cake = happiness, and birthday² + (21 shots) = ???. In front of the chalkboard, a party-worn young woman (Isabel) in a party hat holds a calculator in one hand and a cocktail in the other, clearly pretending to solve the "birthday formula" while surrounded by party streamers, confetti, and half-eaten cake. A couple of her friends in the background wear nerdy glasses and lab coats, raising test tubes filled with bubbly drinks like scientists celebrating a breakthrough. The overall feel is cheeky, vibrant, and joyously chaotic — blending academic overachiever vibes with pure 21st birthday mayhem.

Generated with these themes: 21 birthday, and Maths equation for love and happiness.
