Hey! Name's Zephyrus. I happen to cosplay from multiple series and genres (not just anime, but also books and video games currently). However, Axis Powers Hetalia was my first fandom, and it is currently still near and dear to my heart.
When cosplaying I tend to focus on the aspects of appearance, as well as acting in character...that is when I'm not around friends, because let's face it, I can't be serious when I'm with them, they're too funny. I also, when it comes to more historical things (the historical side of Hetalia, Assassin's Creed, etc) I focus on being accurate historically.
I promise I'm not some serious person, get me laughing and you'll see other wise!
