This whimsical illustration features a bustling multi-level treehouse filled with a diverse group of people enjoying various leisure activities. The scene is segmented into several rooms and outdoor areas, creating a layered, busy composition. Characters are depicted reading books, painting, brewing potions, having tea, and playing, all within a playful and imaginative architectural structure that blends indoor living spaces with dense foliage and trees.
The artwork uses a vibrant, contemporary flat-illustration style with bold, saturated colours. The palette consists of warm oranges, soft pinks, deep greens, and bright purples, contrasted against a clean, white background. The figures are rendered with simple, expressive features and rounded shapes, contributing to a sense of warmth, inclusivity, and relaxation. Light and shadow are simplified, relying on flat blocks of colour to define depth and form within each small cubby-like room.
Various secondary elements enhance the narrative, including birds nesting, a small dog sitting by a dresser, a child wielding a toy sword, and others using telescopes or binoculars to survey the garden. The text "holiyay" is prominently displayed in large, dark, sans-serif letters across the top, while the caption "La cabane dans les arbres | The Great Treehouse" appears in smaller type at the bottom. A small circular icon with a red maple leaf is visible in the upper right corner.
