Looks quite good with a more classic arrangement of main guns.
If you like some suggestions, I'd raise the funnel a bit, getting it to the same height of the aft fire-control tower so the smoke can clear the aft director.
The older 1920s Tosa turrets look a bit out of place on a late 30's design but I have something to improve that look.
I've done this 16.1-inch gun turret for one oy my -yet to be featured- AU ships, you are free to use them in your drawing as well if you like.
