Jem'Hadar Vanguard Dreadnought Cruiser
Here you can see some early style variations. I try to keep the sketches angles similar so I can exchange parts between them. Weapons, armors and other ships can be kit-bashed from here thus keeping the style consistent across the board.
"The Jem'Hadar Vanguard Dreadnought Cruiser frequently acts as the flagship for Dominion fleets, as this commanding starship is just as suited to frontline assaults as it is to leading its fellow starships in strategic strikes from a position of authority."
