Speaking of GSB, introducing the Buffalo class Federation Cruiser!

No custom bullet sprites yet, although the beams are pretty easily done with stock beam designs. The glowing orb at the front is actually a hidden nanomatrix (aka a repair moduale in GSB) being charged up by the infusion powerup. The orb is there in the actual game, but without the glowing.
And without further ado, presenting the entire Federation race:

Cruisers:
Eagle
Buffalo
Rabbit
Panther
Frigates:
Wolf
Puma
Fox
Gazelle
I would have added fighters, but the core would have been too large to have been hidden.
I have 1 more ship done (although weaponless) that I've found from the Scavengers mod.
Introducing, the Broken class Asteroid Ship!

The tractor beam holding that extra bit flickers and glows to be as lifelike as possible.
