Ah, so the sculptor is working on the moulds for the units now, and sent you those Panzerschiffe pictures as an example of the classes he is going to produce for you. As well, he has chosen the Aquila Class CV, Littorio Class BB, and Zara Class CA for the Italians - all excellent choices, IMO.
In terms of prototypes, I indeed see your point. However, later in the production stage, if you feel like posting some of the actual sculpts sent to you by your modeller, by all means feel free to do so. Of course, you may also decide against doing so; any decision on whether and when you can show us some sculpts is entirely in your court. I am just glad to hear that everything is going OK with the set at this stage. 8-)
Unfortunately, I cannot provide you with land (or any) sculpts, as I am not a sculptor. Hopefully, someone else here can help you with that. :|
BTW - If you are considering using the Sovyetskiy Soyuz Class BB for the Soviet Union instead of the old Gangut class (which I certainly hope is the case), maybe this picture will help, as sources for this class are a little harder to find than for most other classes:
