Here is a tighter concept drawing of the Lancer Class Frigate that I am about to start on.
And Yes from the front and side she looks a little like a BSG Viper. On my original sketch it was supposed to be aviper and turned into this. The nacells expand out when in warp and retract when in sublight.

Here is another design that I sketched up while looking at on of my star Wars Titanium ships. (Droid Fighter) and from almost every angle
I looked at it I saw a starship minus the nacelles, So the Spartan class Heavy Cruiser was born.
