Energy mines on a station? Doesn't sound wery smart (like firing nukes on your own soil) And would that make it overpowered?
I am also a little scared of the numbers there... How big is this? I would rather have quality over quantity...
The energy mines were only an example... aside that their use is limited - they are a long range precise weapon
(only a few volleys are always fired and if the enemy jumps out closer it is completely useless

)
About the number of light pulse cannons... It's not overpowered - compare it to Ja'stat (~40) or Orion(~16), the LONAW station also has a similar number of weapon placements - remeber that this is a military outpost afterall, it has to be able to defend itself from 1-2 cruisers...
You asked for it. I think big bad weapon in the central section is way too predictible and old as an idea. And I doubt Narns would be willing to equip that kind of heavy (and expensive) firepower on a station. Since it's tactical uses are severly limited. If the enemy doesn't happen to be in the fov, the weapon is useless.
I think that the x-ray laser would be only a secondary main weapon - most of the firepower should come from 3-6 heavy plasma pulse turrets and some missles.
EDIT the x-rays firing arc would be limited but only on the "bottom" and because of the station "wings", but the heavy pulses would still be able to fight back in these directions
