Create an image of Elon Musk deep in thought, depicted in a Neo-Pop Art style. Capture his intense facial expression as he contemplates groundbreaking ideas, surrounded by symbols representing his ventures like Tesla, SpaceX, Neuralink, and the Boring Company. Use a bright and saturated color palette with vivid shades of red, blue, yellow, and green, paired with bold black outlines, reflecting the Neo-Pop Art aesthetic. Incorporate elements of collage by blending photographs, text, and graphic designs to create a dynamic and visually striking composition that embodies the innovative energy of Elon Musk's entrepreneurial spirit. Emphasize his central role, with various symbols and elements radiating outward from his concentrated expression. Add subtle creative variations to enhance the overall impact while maintaining the essence of the concept.
