don't worry about the engine glows. everything is being colour corrected to red anyway. the engine glows in ROTJ and ESB were red so I see no need for them to be pink in ANH.
yeah, the article is a it biased, but you can't argue with the results they get on battlestar, some top notch stuff, particularly in this latest season. it is an interesting article in itself because of what he says about the work ethic etc in the studio.
