Well, the model is pretty nice. Though if you're gonna have a cargo ship permanently docked there, perhaps something a little more suited to the omicron systems than a albatross, perhaps a firefly or a BWT, if that would be do-able(which I am not sure it is). As for the firepower, increasing Dabadoru's firepower was discussed... extensively... in the betas for this version and it wasn't done with Dabadoru being "hidden" and all. As for the next version, I can see an increase, though I think you may have gone a bit too far.
I've always been in favour of making it a large, ultra-fortified complex built out of ice asteroids, with a Willard-style base at the core. Think Fort Leniex, but icy and smaller, and you're on the right track.
I like the linear design of the second one more, but the first looks like it has better access to the shipyard. I'm assuming the second one would require a ladder to reach the main facility.
I like the first one. I see the ship dock not as a construction yard, but as a repair bay for all the caps that get beaten up by the Order and/or Harbinger. Nice work, good to see people working with stations.
