So far i like the design of this ship, and since it is supposed to be a modern coastal defence ship, you could have a look at the swedish HMS Manligheten..
My coastal defense ships are designed to operate on the Norwegian coast and not up in the Baltic Sea, which means I need a notch better seakeeping safety Manligheten have, with the luminaire she has a small hull I believe that she will be uneasy in bad sea.
Also: top heavy
But she has some lines that are interesting, but I'm drawing a Norwegian coast coastal defense ships that could have been coast at Horten Naval Shipyard. Her size is limited to the size of the shipyard's dock. I would later draw a version where the contract is awarded to one of the large private shipyards along the coast.
