Here are the Talliscan from Kallistra's Space Dreadnought 3000 range. They were the supposed inheritors of Guardianship of Sector 7 until it was decreed that they had to fight for it, like everyone else.
Aesthetically, they look a little like klingons with the boom and large back. Painting them was relatively straightforward with a bronze basecoat followed by a copper drybrush. Guns were painted with steel, followed by a chrome drybrush. Gun orfices were painted black and the engines were painted with Boltgun Metal and the engine glow was painted white.
The ships had some nice detail and were fun to paint.
