I just love Historical Hetalia and you've done a great job here, really^^ !
I'm definetely not a pro, when it comes to differ between uniforms, so I really admire your work, expecially the details.
where did you get those references? I´ve tried to do something similar( traditionally for a friend) but even though I got an idea of what they were wearing, there wasn´t a clear uniform for most of the ones I searched for. Is there a website were you can find these?
But the uniforms are really detailed and the characters have nice proportions. Well done!
