Definition through line art
The ship is still a bit of a mess, so we need to define the individual pieces and shapes into a coherent whole. Focus in on the guts of the ship where all the earthly belongings of the pioneers are carried. How are the engines yoked to the main craft? These details come into focus at this stage. At this point I’m more interested in making the design look cool. The story of this being a space wagon is established, so now it’s time to fill in all of the fun sci-fi gizmos!
Next I add in more line-art and decide that the ship doesn’t have enough girth, so I drop the front of the main hull down to round the ship out. In my backstory, this vessel was put together with used or salvaged components, which is why neither engines are identical.
