This is the top of the Galactica, you can tell by the fact that you can read the name of the port nacelle.
This is the bottom.
Here are other shots.

If you want the weapons to be more like Galactica's you should make the point defense guns fire like the meteor gun, which fires like a shot gun, just make it do so rapidly.
Galactica seems to turn slightly too fast in the new mod. I like it with no shield and I really do think a more shot gun like effect might help.
