I'm very sad to hear Hetalia anime series might not have more than 100 episodes, even if we'll still have the manga and webcomics, I'll miss the seiyuus' voices so much, I really love them! It'll be sad not hearing ve~ or da?~ or bakabakabaka or aiyaa or aru anymore. I do hope there will be more episodes!
Another series I love as much, even if I gave up watching it (it's over 350 episodes already!), is keroro gunso, all the characters are so adorable! I do miss them too, sometimes I watch one or another new episode or movie, but it's hard to catch up now. And while I was sad about hetalia, I remembered how I gave up watching keroro, and wished hetalia could be as long keroro~
So I did a cross-over fanart between hetalia and keroro ( I think I never did so many characters together!). It was so much fun to do!~ It was hard too, because some charatcers were easy to match, like China needed to be Koyuki, and Canada was meant to be Dororo, and France was good for Saburo-sempai, but the other characters would match more then one, and it was hard to choose and keep some characters out. All in all, I'm happy with this drawing, it might even be my favorite one so far ♥
