Card models are great.
heres the thing though.
its a new skill set that needs to be developed in the usual way, start small and work your way up.
I'd say the same thing to any modeler who wants to try a plastic sailing ship and has their eye on that Revell Cutty Sark. Or first time wood anything more ambitious than a solid hull schooner.
As our former mayor famously said, "a man has to know his limitations".
One huge plus for card models is that you can buy them online And get them instantly, if you have access to a larger format printer.
The commercial ship modeler have a real resource.
