I always find the "Brett the copyist" discussion fascinating, because that was his style. When I started reading 2000AD regularly, Ewins was the main man. His Rogue Trooper, his Dredd, his Anderson, his Dark Judges. I neither knew nor cared that some of his figures were heavily referenced or even exact copies of other artists' panels: it all looked like Ewins to me, and it all looked good. And I still feel that way: his chunky-tech heavy-black pages are bold and lively, and everything fits together, the borrowed bits and the new bits, all making for a good looking well-told strip. Even the re-using of blown up pixelated photocopies of his own work on Bad Company works within his scheme, actually becoming something interesting in its own right rather than a 'cheat'. A style born of necessity, but one that really works.
Incidentally, that Judgement Day cover not only graces one of the best RPG modules I ever played, it's also a superb image, regardless of the Dredd being traced from McMahon: it's inked and coloured n such a way as to form the heart of a great new cover . And it's also perhaps worth noting that all the interior illustrations, and all the interior art in the main boxed set, are reprinted panels from the comic: at least here we got something partly new. Stick an 'after McMahon' box in the corner and we're good.
I can of course see how that is/was irritating for the artists concerned, and what the wider issues are, but I can't feel that way myself. When i look at the work I just see good comics.
