I like the concept, very cool looking. Though, I gotta say, I don't like the wasp waist, that's a very big weakness in the design. One, it doesn't allow for very fast maneuvering, and two, a single, well placed shot could totally disable the whole ship. Also, is the "mandible" in front a weapon or a hanger? If it's a hanger, then fail. It would be much easier, and more efficient, to cover the whole outside with fighters. Then they could just "drop" away from the mother ship and fly at the target. If it's a weapon, then you've done a good job. That justifies the mass to weapon ratio for the ship.
