Here's the inital blue pencil sketch of a project I'm doing.

This is the un-corrected ink drawing.

Line art cleaned up and flat colors have been laid in.

Some background tones laid in and a few color changes.

The background is more or less finished and began some work on the figures.

I finished the tones on the main figures and changed the spaceship colors. I also changed the ink lines on the background elements to blue.I think this is the final (for now at least).
