The front cover of the greeting card should be an abstract explosion of color and form, reminiscent of a collaboration between Kandinsky and Miró with a dash of Pollock’s chaotic energy.

**Background**: The background is a swirling sea of vibrant blues and aquamarines, echoing the crystalline waters of Corfu. Layered upon these are broad strokes of golden yellows and sandy beiges, suggesting a sun-drenched beachscape.

**Foreground Elements**:

1. **White Wine**: Center stage, an abstract representation of a white wine bottle and glass. The bottle is a bold geometric form, a fusion of Mondrian’s straight lines in black, white, and splashes of pale yellows. The wine glass beside it is a sinuous curve of translucent blues and whites, capturing light in fractured, cubist reflections.

2. **Cats**: To the left, a pair of feline forms dance in de Kooning-inspired motion. The black cat is a silhouette of jagged edges and fluid lines, scattered with tiny, Pollock-like specks of deep reds and oranges. The grey tabby is composed of swirling grey tones interspersed with stripes of silvery white, almost like Richter’s brushstrokes.

3. **Shopping Bags**: On the right, an abstract cluster of shopping bags represented by overlapping rectangles and trapezoids in bold primary colors - reds, blues, and yellows. These forms are arranged with Mondrian-like precision but twisted with Miró's whimsical touch.

4. **Number "70"**: At the top of the card, the number "70" is crafted in a large, bold Rothko-esque block of deep maroon and contrasting bright white. The figures are slightly irregular, echoing Twombly’s line work.

5. **Corfu Element**: In the upper left corner, a simplified outline of Corfu’s coastline weaves into the abstract forms, with lush greens and teal outlines suggesting the island's lush landscape.

6. **Text "JANE"**: The name "JANE" is artistically integrated into the scene, positioned in the sky area, as if formed from fluffy white clouds. The letters are curvy and soft, rendered in a minimalist style reminiscent of Agnes Martin's subtlety, blending slightly into the background yet standing out with a faint shadow.

The composition overall is a dynamic, layered tapestry of forms and colors, creating a vibrant, abstract birthday celebration that embodies all specified themes in a harmonious, eye-catching manner.

Generated with these themes: White wine, 2 cats- one black and one grey tabby, 70, Shopping in bags, Corfu, and Beach.
