I really, REALLY like the way the artist draws the KanMusu's in these artworks. Their uniforms are feminine (but modest) while still maintaining a realistic "Navy" feel. Moreover the differences in uniform between the classes (BBs look like Ensigns/Midshipmen, CLs/CAs look like NCOs/Petty Officers and DDs look like normal enlisted Seamen/Sailors) are a very nice touch as well. I am very impressed and pleased with this set up.

I wonder how it is that Kirishima is the tallest of her sisters, even by a smidge.

Maybe it's judging by Kirishima's Kai Ni art, in which she looks a bit taller than her sisters
