Honestly it DOES look like a mercenary gunship. Also, not saying what faction you had in mind leaves US at an impasse as well, since each faction has its qualities that tend to be evident. For example, that ship wouldent fit in with the BAF or liberty, but would be passable as a merc ship or the order or zoners even.
It looks flat, and difficult to balance properly... the only other thing I can say is that the shape of the vessel doesn't fit Freelancer one bit, and that's a bit of a shame since it's a fairly decent looking model.
At any rate, it doesn't belong in Freelancer for the same reason that the other odd ships doesn't.... unless it's a Kusari vessel, but even that would be hard to swallow since it doesn't look like it belongs in that niche.
