Hello! I post 99.99% all things hetalia-related here. I have a step-by-step guide on how to ask pixiv artists permission to post their art on tumblr over there just above the tag page. My tag page is there in case if you want to look up a ship or character, you'll find it there! I'm in the process of going through my 30,000+ thousand posts to delete any art I've posted without the artist's permission, so please bare with me. And if you see any of the old art I've posted that doesn't have the 'permission given by the artist' caption, please do not reblog it. Thanks and have a wonderful hetalia life!
(psst~I also track the hetalianforever tag)
