Awww yeahhh! This is another awesome piece from you :D.
I really like the concept (even if it's a commission piece!) and how you execute the illustration. It does look like a giant architecture that left its home in a hurry, and it's kinda cute that it left a hole behind, since most spaceship launch doesn't do that. But obviously this one is pretty big, city wide big, so no wonder that it would create a vacuum in its stead.
The animation and the step by step gives this post cherry on top of the ice cream :D.
It was like a big dome in the city that extended also waaaay below the surface. That's how it was built. Thanks kind scrwls :D
