Imagine the scene is set in an enchanted forest, where the natural elements have been subtly transformed to incorporate the birthday, yoga, sauna, and shower themes.

**Foreground Elements:**

1. **Yoga Mat**: The yoga mat lies at the forefront, intricately detailed with Aubrey Beardsley-inspired swirling patterns, intertwining vines, and flowers. It's a deep mossy green with hints of lavender and gold, giving it a magical aura. It rests on the forest floor, partially covered by fallen autumn leaves in shades of amber, crimson, and sienna.

2. **Birthday Cake**: Perched delicately at the edge of the yoga mat, the cake stands tall and whimsical like a Maurice Sendak tower. It's layered with unusual flora-inspired decorations – think edible petals and sugar-spun vines. The cake's tiers are in pastel colors – rose pink, sky blue, and buttercup yellow, with each layer more ornate than the last.

**Middle Ground Elements:**

3. **Sauna**: A quaint wooden sauna hut is nestled between two grand oak trees. The wood has an N.C. Wyeth ruggedness, textured with knots and organic grain patterns. It emits delicate wisps of steam that rise into the canopy, twirling in Maxfield Parrish’s ethereal light – hues of turquoise, periwinkle, and hints of shimmering gold that play on the steam's surface.

4. **Shower**: Beside the sauna, a quaint, almost Beatrix Potter-esque shower is constructed from a hollowed-out tree trunk. Water cascades gently from a leaf-shaped spout, catching the Edward Gorey black and white crosshatch detailing, reflecting the intricate natural designs on the bark. The water sparkles under a whimsical overhead sunbeam that filters through the foliage.

**Background Elements:**

5. **Forest Canopy**: The backdrop is lush with an Arthur Rackham canopy, where tree branches twist and weave into each other, forming a natural tapestry. Dappled sunlight filters through, casting an ever-changing pattern of light and shadow across the scene, evoking a Gustave Doré mystical quality.

6. **Animals and Inhabitants**: Small creatures, reminiscent of Quentin Blake's charming sketches, populate the scene. A squirrel perches atop the sauna roof, inquisitively gazing at the festivities. A pair of rabbits, elegantly drawn like Beatrix Potter’s, nibble on birthday cake crumbs. A wise old owl watches serenely from a high branch.

This fusion of birthday celebration, nature's sanctuary, and fantastical elements invites the viewer into a detailed, surreal world, echoing the elegance and intricacy of classic illustration while celebrating the whimsical joys of life.
