Hello Tempest
I like it. Already closer to the mark (bow shape!) than Rurik-2's old drawing that still spooks around in the www.
Two little things, if you don't mind:
a) I'm not wholly sure about the rudder - right now it looks like it is hinged to a fixed part, but Groener and Breyer depict it as one-piece, rotating around the shaft.
b) I'm also not sure the sheer of the hull continued all the way to the stern. Right now, deck height gets dangerously low towards the stern - either the upper edge of the armour belt also tapers down or the weather deck aft was level (that's what I believe). Maybe a problem with the source drawing. For whatever that's worth, my 1/700 resin model of Mackensen has a level weatherdeck aft without sheer.
Of course, if you have firm data that disproves me, I revoke everything and claim the opposite
Greetings
