Chronova Head Shots

I am trying to see if I can get my own secret comic project "Chronova" off the ground.  These are various character designs from the comic. Allow me to go through each head shot one at a time.

From the top left to right, it's the main character Samantha Lombard, femme fatale Elesa White, and Vanessa Geary, the resident medic officer for the good guys.

From the bottom left to right is media mongul Kat Valencia, hapa Mica Tirado, and the chief antagonist of the story, Agent Knox.

Who are they? What does all of this mean?  It will be revealed in the next few months.
