Create an image of a technologically advanced robot artist painting a vibrant portrait of a majestic lion in the midst of a futuristic jungle.

In a jungle of the future, where the flora is glowing with radiant, bioluminescent colors and unusual geometric shapes, a technologically advanced robot is immersed in the process of creating art. This autonomous machine, a robot artist, equipped with innovative tools and gadgets, gracefully manipulates a digital paintbrush with its sophisticated mechanics. It is intensely focused on painting the portrait of a majestic lion, who has a king-like aura about him. The way the metallic artist captures the details of the lion's mane, the spark in its eyes, and its noble posture is intriguing. The backdrop, the jungle, and the subject, the lion, juxtapose the organic world with the world of advanced technology.
