Most anything by Mike Mignola is somewhat similar in style if not tone. See his Hellboy mini-series for that.
Or if you want Batman, there have been 2 recent mini-series by Matt Wagner in a similar vein. Batman and the Monster Men was the first and Batman and the Mad Monk is the one currently going on.
Invincible is a good series with a very illustrative style of artwork. Any of the Kevin Smith/Phil Hester Green Arrow books have a similar style and good story. Scott McDaniel is someone with a similar style and he's currently doing the Green Arrow series.
