Ok, so thanks Bezo, the black boot topping will be gone, first from the ships i will post from now on then from the ones already done when the first post will be updated with all ships and text (so basically when all Takaos will be drawn as planned).
and as for your Chokai model as a template, well, if you had those pictures on warshipmodels it could be
and if it's really there i could use it for the 1937 drawing you asked
And to get back on the cruisers, here is Maya as of 1933 (with revised waterline)
and don't panic for the orange line floating above the aft guns, as you can see there is no seaplane; i must draw the Nakajima E8N "Dave" before adding it.
