Very nice work, but shouldn't she have the red underwater hull by this time? I noticed a previous drawing of Bretagne in 1921 had the red underwater portion, and this is supposed to be in 1922-1923. Just curious.
I'm not sure of the exact transition from green to red, but this is a 1917-1919 study expected to be complete in 1922-1923 so it might still be green.
