I knew that there would be a small but large enough group of characters that several would be in frame a large portion of the time. So my initial attempt was to concentrate on the faces and shapes then work on the overall look of the space suits. Later down in this post there will be a partially cleaned up page to show the changes I made from this picture to the comic itself.
After getting the human designs down, my next endeavor was to work on a few of the more technical stuff, so I did a few sketches of the spaceships and an important prop to help me visualize the story.
After these preliminary sketches I went about the most fun aspect of the story, the alien that attacks the crew, I quickly sketched out several versions of the alien until I got something I felt interesting and appealing to me.
And finally here's 2 partially sketched in pages of the comic before I had to drop the project.
