Of course not, add away (<-- erm, now this just sounds funny)! ;)
I don't have that many friends cause I'm shy about adding them and I haven't been around fandom for long, only since last year. Plus I'm not a Drarry fan (blasphemy, I know, we've got an infidel here, let's burn the witch!), I prefer obscure pairings like Ron/Draco. :)
But I don't mind having Drarry friends (I think most of them actually are), so I'd be happy to friend you. I don't read Drarry, but I will look at any good art, cause I happen to believe it transcends the borders of taste. :)
And I love the next generation, fics and art! :)
