Cover art for EARTH 2.0: PRISON PLANET  by William Crow Johnson. 
It's really fun to do a hardware piece every once in a while.
The idea behind this ship was that the engines (fusion drive) are inextricably linked to the weapons -
thus linking the power-generated and power-expending parts. They are connected by the mechanical detail
and allow the green that glows like the menacing "War of the Worlds" Martian machines.
