From establishing the basic premise of the story, I moved to some more detailed sketches of the specific scenes I had in mind to work on layout and content. I decided to use illustrated perspective to tell my story.
For the sake of brevity, I'll only show the process for a couple of frames from the first chapter. The story begins with the idea of a spaceport on an earth-like planet, which is basically an airport but for rockets. In the first frame we see our main character looking out over the tarmac with the hope and expectancy, yet gravity (no pun intended) of his upcoming journey with the activity of a busy spaceport going on behind him. The second frame is an overview of the active spaceport from the outside.
