I didn't really have much of a appreciation for Ron Smith when I was a youngster reading 2000ad. Mike McMahon and Brian Bolland were the 'flashier' artists to me back in those days. I really gained a better understanding and appreciation for Ron Smith when I got older...pretty much the same thing I saw with Jack Kirby's art.
Ron Smith, for me, is and was the definitive Dredd artist of the 80's. He added a certain 'American' look to Dredd. Almost superhero-ish without being a superhero. And his near impossible poses worked perfectly for him. Something he has in common with Kirby. To me Ron Smith is the english jack Kirby.
