I see that you’ve added a cone to the tip of your rocket so that a parachute can inflate when the cone breaks away. That way, the rocket can return safely to the ground. It’s an important detail to include. Good stories also include important details like the one you’ve drawn.
Isn’t it too bad that Martin’s rocket never had the chance to use a parachute, but rather exploded instead due to extra big fuel cells? Maybe you can write a story about rockets with a different ending.
