Whoah... we finally get the main character... now all we need are Isuzu Hana, Akiyama Yukari, and Reizei Mako.

The rest would be just minor named and unnamed characters.

As an aside, I organized the pool according to the wiki Girls und Panzer to make it easier to find characters as well as those who are still missing...

Surprised Miho didn't get a more epic picture like Maho did.

I believe this drawing is the front cover of a artbook for the Nose Art series.

Abazu's twitter shows a teaser of Miho wrapped up like a Boko for her drawing.

Yep. It seems Miho shall get TWO nose arts.
