By the way, I got this one from an episode, a deck-count. Looks like it got a total of 7 decks.

Yes, the similarities are there. But doing outwards is a logical step. Assuming you cannot built upwards or downwards (which, with the Ournall-class would be a hassle), building sideways extending booms is feasible.
But nonetheless, the inspiration is visible.

Nice work. I remember the Immens from way back then.
I admit I'm a bit out of the loop on Picard... What did they rip off your station?

The railing reminds me to the bridge of the movie submarine Red October. The central command area of the beridge was recessed about two steps below the rest of the bridge and had railings all around (except of course the steps). It's a great idea to give a level of separation between "workstation" and "thinkstation", but beyond that, it's of little use other than for people to bang their heads instead of falling on the captains lap whent he ships gets haken up.

The level of detail is, as usual, absolutely stunning.
