This is a vibrant and detailed drawing of a helicopter flying in the sky. The helicopter features a striking yellow body with a bold red stripe down the center, as well as two rotors on the top of the craft. It is gliding gracefully above a sprawling cityscape. I would suggest using bright and warm colors to bring the scene to life. A brilliant yellow to highlight the helicopter's body, an energetic red to accentuate the stripe, a darker blue for the city buildings, a cheerful green to represent parks and foliage, and a white to suggest clouds and light reflecting off the craft would all work together to create a captivating image.
