harry potter is my hobby

These are some of my favorite sites for Harry Potter fanfiction. If you're just curious, I suggest you check out Fiction Alley or Fanfiction.net.
Some excellent HP fanart.
A couple of the fanfiction sites on the list above also have excellent fanart pages. So if you're looking for more fanart take a look at PSA, Armchair Slash, or Bottom!Draco Emporium.
