This is a dreamy illustration by artist Apofiss. The main subject is a small black cat sitting quietly on a rock at the bottom of the deep sea, gazing forward with clear, slightly melancholic eyes. The cat's silhouette is outlined by a soft yellow-green glow, as if it is emitting light itself, contrasting sharply with the deep blue-green background. Several crystal-clear bubbles float up from its side, creating a weightless and serene underwater atmosphere. The overall color palette is cool, accented by warm light, conveying both the mystery of the deep sea and a sense of lonely healing through the cat's presence.
