Create a painting background for Austin city, only focused on the Texas State Capitol. Ensure the architectural integrity of these structures is maintained. The color palette: #00B140 for bright verde, #000000 for black, and #FFFFFF for white. The artwork should be vibrant and youthful, suitable for a young audience, and should not include any human figures. The use of bright green and black should be prominent, with smooth gradient effects. The overall composition should be dynamic and visually appealing, capturing the energy of a modern cityscape
