3 point perspective process

 Here is a 3 point perspective piece I did based off of 2001: A Space Odyssey, when the Monolith is found on the moon and becomes active.  

I thought It would be cool to show how the piece transformed from basic line work to a finished, colored piece. Enjoy :)

Perspective Work

Here are two different variants on 2 point perspective, the first being Two point vertical and the second standard 2 point.
