Try again?
I'm going to teach this to a friend to see if it actually works as well as planned.
Might even be able to work in the Italy arm going through the space for the salute, but that's only a maybe. I wasn't even thinking of that when I made those in the first place. The Germany and Japan moves should be done facing each other, so that works out, and for America's move, both the moves that will be happening in front and behind will be facing away, so that's like the actual march too. The England move should be done with a purposeful glance behind, so as to tie in with the one behind it.
The last bit is just like the original march, but I've been toying with the idea of altering the last pose.
