Oh I have soooo many that I love. Kevin Maguire, who pencilled the Justice League's late 80s reincarnation. His style was so clean and simple and he had an amazing talent for facial features - especially considering how much humour was involved in that run.
George Perez, and Phil Jiminez have similar styles that I find very pleasing, especially when they are drawing the Greek Gods and Wonder Woman's amazons.
Alan Davis, I think I first encountered his work in the pages of Captain Britain
, and later in DC's The Outsiders
. For a quick look at his lovely pencils I highly recommend picking up The Nail
, which is a kind of alternate-reality Justice League tale.
Adam Hughes' Wonder Woman covers are just incredibly beautiful - have a look at the attachment below, to see what I mean.
