I have been deeply involved with the defense of Earth and all kinds of other planets and realms for quite a few years.  It is my experience that there really is some sort of IPJE - Intergalactic Peace and Justice Enforcement.  This colored pencil painting is of a three person patrol vessel capable of light speed.  Hopefully, it is obvious there are IPJEs at other levels of capabilities.

This is an angle view that intends to better represent the overall shape and contours.

I had a blast learning and figuring out how to do this.  I am now working on others.
