It's from Umineko no Naku Koro Ni and the character is Furudo Erika! It's my all-time favorite series (or thing) ever. I've been obsessed for...years? Haha. Anyway, I know it might be a bit troublesome, but would you consider tagging and submitting the picture to a couple of groups on DA? Just so people can see it (and like me appreciate it). I always want to add more art to this fandom.
Could you edit in tags for "Furudo Erika" "Umineko no Naku Koro ni"? And as for groups, and if you feel like it (that goes for doing anything with the art since it's your piece), could you submit it to either or both of these?

They have a rather active feed and it seems to be the best way to share the art.
Also, would you care for a tip? Seriously.
