I used to dream that the universe was way different. Space is filled with rock and dirt. Planets are just air-pockets in the dirt. The sun and the moon would orbit the center of the planet. The stars in the sky are just city lights on the far side of the air-pocket.

No outside sources were used.

I did this about 7 years ago, it was for line practice. I never got around to shading or coloring it and to be honest, I never really figured out which would look best on it. The drawing took over a week to do, had to restart a couple of times and lots of erasing along the way.

Note: to do this type of drawing, you use a light board and graph paper, you do your drawing on a paper over the graph paper. You do 1/4 of the drawing, then you use that as your visual guide for the rest in reveres
or upside down.
