Cozy neon gaming room with boy and loyal golden retriever

A dimly lit, intimate space with a young boy's dream gaming setup, illuminated by a mesmerizing neon glow emanating from the walls and a glow-in-the-dark star map on the ceiling, transporting him to the magical world of Hogwarts; vintage Harry Potter posters, such as the Hogwarts crest and a Quidditch match, adorn the walls alongside sleek gaming posters featuring his favorite characters and consoles, while a worn, plush couch and a gaming desk made from an old wooden door dominate the room's center; a majestic golden retriever, its fur glowing softly in the neon light, lies peacefully on the floor, its paws curled up as if guarding the boy's gaming throne; the entire scene is rendered in a dreamy, underpainting style, with loose brushstrokes and soft, ethereal colors that seem to dance across the canvas, as if the very essence of the boy's imagination has been brought to life.
