The scene is a whimsical, intricate tableau that blends the birthday theme with the suggested eclectic elements. Picture a vibrant, detailed setting that resembles an expansive, yet intimate dining room where every element seems to dance between reality and fantasy.

**Foreground Elements:**

1. **A Mother in Action**: At the center, a mother character who is part 1920s flapper, part DIY enthusiast, is caught mid-hammer as she nails a 'Happy Birthday' banner above a doorframe. She wears a chic, vintage outfit with a tool belt slung around her waist. Her hair is styled in a short bob, and she sports round, oversized spectacles.

2. **Feral Children**: Surrounding her are several feral children, playful and wild, who are depicted as half-human, half-canine creatures. They have shaggy, unkempt hair and wear mismatched clothes that appear as if stitched together from leaves and twigs. One of them clutches a balloon shaped like a moose, hinting at the Canadian theme.

3. **Birthday Cake**: A grand, slightly lopsided cake sits on a table made from a slab of wood balanced on two sawhorses. The cake is festooned with candles shaped like tiny Cyprus trees, complete with miniature pinecones and tufts of snow at their tips.

**Background Elements:**

4. **Home Renovation Details**: The backdrop includes partially painted walls, where one side remains in rough plaster, and the other sports a striking mural of a serene Cypriot coastline, reminiscent of Beatrix Potter’s detailed landscapes.

5. **Canadian Touches**: Maple leaves, artfully strewn, are scattered across the floor and around the scene. There's a stuffed beaver sitting on a bookshelf in the background, and a small painting of the Canadian Rockies hangs crookedly on the wall.

6. **Furniture and Decor**: The furniture is an eclectic mix of styles, with an ornate, slightly Victorian chair (a nod to Arthur Rackham) juxtaposed with a minimalist, modern lamp casting a soft glow.

**Color Palette and Texture:**

- The color palette is rich and varied: earthy browns and forest greens intermingle with flashes of vivid red and maple gold, evoking an autumnal Canadian landscape.

- Textures vary from the smooth gloss of the cake's icing to the rough grain of the wooden table, creating a tactile richness in the illustration.

- Use stippling and cross-hatching in an Aubrey Beardsley-esque manner to add depth and detail, especially on the children’s clothes and the mural.

This card cover should burst with detail and energy, capturing the surreal intersection of these varied themes with a charming, quirky flair.
