And I think the wings need to look more Liberty-ish, other than that its pretty good.
I find it funny when people ask this... Remember, your looking at an unskinned model of the thing, and given common sense you can figure the cockpit is going to be in a generic location.
The engine wings are fine to me. The main body of the ship looks a bit lacking in detail though. Perhaps adding two smaller wings towards the nose (something like the Avenger's top fin)
Using the Fafnir itself (as I don't have the model) and the Avenger's top fin (since i'm not going to make something more fitting), as reference:
Eh you get the idea.
FYI, the hexagon bits are engines... Liberty Engines if you notice on the Guardian / Avenger / ETC they are hexagonal shaped. In addition, as Kazinsal said, If you make something that is by design based off of another design, it -will- look similar to that other ship, by design.
