Frank *ucking Quitely (Vincent Deighan). Flex Mentallo, Invisibles, All Star Superman, Millar's Authority, JLA: Earth Two, Sandman: Endless Nights.
Best artist in comics, hands down. There's a distinctly unique aesthetic to his artwork that just GETS him. I can't quite put it into words. I think there's a reason he works with Morrison so often, aside from them both being Scottish- his work just EXPLODES with love for the superhero genre and for the sheer fun, cleverness, and power of comic book.
But I could understand why someone might not like him, especially when he's in his more cartoony mode.
benes has gotten mighty lazy of late, though considering the level of writing in jla atm, i doubt any writer would try that hard...
ivan reis is still knockin em out of the park on green lantern...
i'm loving caselli's work on initiative atm...
for me mike choi is one of the best x-men artists ever, and is quicky becoming my favourite (my favourite being whilce portacio)
