Any Comic Book/Graphic Novel Recommendations?

I'm new to comics.  Just got in reading Watchmen.  So I've read Watchmen, V for Vendetta, and The Walking Dead Book 1, and I loved them all.  Currently I'm reading The Walking Dead Book 2 and From Hell.  Then after that I'll probably just continue with The Walking Dead series. 
Btw I'm not a fan of superhero comics, but if it's something that kind of redefines the superhero genre and is good I may be interested.  I open to all suggestions.

You might try looking at this other topic for some ideas.
