The thing is, the model showcased so far is more the Argonaut and not the Narwhal/Nautilus. These last two boats had a different gun platform, which did not extend and make a rounded shape over the hull. There is also a more noticeable "bounce" along the hull, in the centre of it, which I don't see in the real subs
It could also benefit from a bit more smootihing of some edges, maybe by adding some more polygons?
Please take this just as constructive critizism, I like the model so far very much.
