Anything by Brian Azzarrelo is worth taking a close look for sharp dialogue and dark storylines - 100 bullets,Joker,Batman-Broken City
Grant Morrison for pushing new ground - All Star Superman,WE3,Arkham Asylum
Mark Millar excel in bringing Hollywood Blockbuster sensibilities to comic book - The ultimates,Wanted,Ultimate FF
Garth Ennis a little crass but still worthwhile - Preacher and Punisher
Hiroaki Samura - Blade of the immortal.Not your usual vengeance story.
Hiroki Endo Eden:It's An Endless World unofficially it's dubbed the best manga in the world.If Akira is your cup of tea,must give this one a try.Bleak and shocking to the core.
For pretty artwork do give Shaman Warrior a try.It's one of the best drawn Korean manhwa.Park Joon Ki artwork remind me a lot of Travis Charest where you get to see tremendous effort and passion being put into it.
