An impressionist-style portrait of a futuristic astronaut tending a vibrant, steampunk garden inside a transparent floating bubble, surrounded by a cosmic landscape filled with swirling nebulae and distant planets. The plants in the garden consist of bioluminescent flowers and mechanical vines, each with intricate clockwork blooms, glowing gently under the starlit sky. This scene blends elements of Monet’s brushwork with Jules Verne’s imaginative machinery, highlighting themes of harmony between nature and technology, as the astronaut, dressed in an ornate, gold-accented spacesuit, delicately waters the exotic flora. The visual is rich with contrasting textures and colors, featuring the soft pastels of the impressionist style against the sharp, metallic edges of steampunk design, all encapsulated within a futuristic sci-fi realm.
