I love the shape and look, the turrets look BA, and the exterior detailing is fantastic!
My biggest issue was unsuccessfully trying to find the AI blocks to turn on the big cannon turrets, if anyone can message me or respond with where to look, I'd greatly appreciate it! :)
I did have some trouble with the hangar bay door logic being a little wonky, which may have nothing to do with the builder, and everything to do with Starmade still being in Alpha.
The only other thing I can say is, I'd recommend greatly enhancing the network of AMS turrets. For fun, I took this up against a light missile cruiser I use as a combat test to see how fast I can kill it and actually lost pretty badly.
I don't hold that against the builder, I'm guessing this ship is designed for a threat environment that consists of small numbers of very dangerous missiles, not salvo after salvo of massive swarmer volleys.
Still, this one is getting parked next to my main shipyard as a inspiration in detailing and a source of ideas in my own builds :D
