Eh.
The cockpit visibility from this thing is a lot better than in most FreeSpace ship designs, although I would criticize the front visibility more than rear in this case. That massive nose and payload bays will cover a fair area of view to the front, but contrary to most other FreeSpace ships, visibility over the shoulders is actually pretty manageable. It's still not exactly fit for a combat vehicle but better than most other stuff, so there's really no reason to criticize that here.
As for the centre of gravity/disorientation comment - you can't judge the centre of gravity visually without assuming that the ship is mostly homogenous as far as density goes. That may not be the case at all. The engines could easily be significantly more massive than the payload bays at the front, which would pull the CoG towards the rear. You could just position the centre of gravity below the cockpit while converting the model and SAY that the engines are more massive, which explains why cockpit is where it is.
That said, even if these were valid concerns, they wouldn't be good enough reasons to change the ship design. Aesthetics would be better reason, because this ship - like most others - is simply not designed for realistic demands that space combat would put on it.
Actually, it might be sort of interesting exercise to design and model just such fighter craft...
