Hey Von Frank, really like your mod release. Love the color scheme, the widescreen and the ship selection. Stability is also a huge plus. The mod feels very stable.
Some constructive points of improvement if you are amenable to them.
The only show stopper I see so far, is the Romulan Warbird feels to me to be too strong as currently built.
I did a test where I stipped away all but the four "Tactical.Projectiles.Disruptor 4") cannons to observe how much damage the ship was able to cause and how much sustained fire it was able to generate. Additionally I tried to disable/destroy these cannons to no avail. You can review the test here.
I looked thru DS9 for Galaxy vs Warbird encounters and found none surprisingly, while TNG has many, S310 Defector, first a single Warbird vs Galaxy encounter is presented but the Warbird moves off, later in the episode 2 Warbirds decloak and pummel the Galaxy but do not destroy it because they want to capture it. However, 3 Kvort Battle Cruisers more than even the odds against the Romulans when they decloak making it 4v2 Warbirds.
in S3E15 Yesterday's Enterprise, It is stated 4 Warbirds vs an Ambassador class make the odds certain the Ambassador loses. (An Alternate Dimension Universe Episode)
S3E20 Tinman, the Galaxy encounters 2 Warbirds, first one attacks the Galaxy, does significant damage but mainly cripples it in order to get at Tinman first, is destroyed by the space creature, the 2nd Warbird threatens to attack the Galaxy but the episode is resolved without further combat.
S4E11 Data's Day It was thought an Federation Ambassador (person) was abducted in a faked transporter accident but turned out it was a Romulan Spy, Anyway the Galaxy moves to intercept and possibly engage a single Warbird, a 2nd decloaks, stacking the odds against the Galaxy, it is reported 3 more Warbirds are entering the sector, probably hours or minutes away. When it is revealed the ambassador is a spy, the Galaxy withdraws.
From these incidents I conclude that a single Galaxy vs a single warbird is not a decided outcome match and while the Warbird might have an edge the Galaxy should certainly be able to be competitive. It is also inferable that 2 Warbirds vs a Galaxy is too much for Galaxy to handle.
So with all that said. I feel that cutting the firepower rate back by 50% of disruptor cannon weapon alone would probably bring the two ships into better balance.
The only other things I was ready to comment on were the photon torpeodes. As built they do not seem to ever miss, they also seem to move and track really accurately and fast. It might be something that could be adjusted. I tried to target the weapons hardpoints and they seem to be protected exceptionally well so maybe they could be made to be more exposed as well?
