Try to watch:
-Elfen Lied,
-Vampire Princess Miyu(pretty old but really great one. I suggest OVA version, but'normal' episodes can do it too...)
-Kuroshitsuji is just nice
-Maybe InuYasha(manga is better anyway)
And many others- it'll be easier to give examples if you describe your intersts(for eg I really like stuff like vampires, demons, fantasy climats, bishonens:P etc while bio mechanics, mechs and so on aren't my favourites
)
