Ross is just incredible... His renditions of the heroes always look to me the way the characters really *should* look if they were real people.
If you ever manage to pick up the Kingdom Come collected trade paperback (which I just cannot recommend enough) there are several chapters of 'special features' in which Ross describes his working methods and the real people (often famous people) that inspired the appearance of many of the heroes in his work. http://www.comicbookresources.com/re...tor_Fan_Pages/
The above link has a good list of pages devoted to some of the most highly regarded comics artists in the biz.
Here is Adam Hughes' website, check out the other Wonder Woman covers - they are all uniformly great. http://www.comicbookpros.com/adamhughes/
