Hyperrealistic 1950s Astronaut Battle Oil Painting

A hyperrealistic oil painting in the style of 1950s artwork, featuring a blonde woman in a tight-fitting, white astronaut suit, standing in a dramatic pose amidst a chaotic scene. She holds a futuristic-looking pistol, firing at an army of orange, robotic astronauts that surround her. The robots are depicted in various states of destruction, with some exploding or disintegrating. The woman's face is set in a determined expression, with a hint of a smile. The background is a deep, rich blue, with subtle brushstrokes and texture evoking a sense of nostalgia and retro-futurism.
