For the light cruiser, with its bulbous, industrial look, I concluded that ships like this would be a mainstay of the Vogon Construction Fleet.
I painted this entire vessel with a bright orange. That made it look too ... orange, but a brownish ink wash took some of the orangeness away, as well as bringing out details on the ship.
I then drybrushed with a yellow ochre color, to give the ship a little more depth and convey a worn appearance. I'm happy with how this ship came out. It will make a nice target for pirates when it's not constructing hyperspace bypasses.
I still have one more Sathar light cruiser to finish painting. I'm out of time, so I'll post more photos of the two completed frigates later on.
