You know, ironically, there's at least one place where Lucas should have tweaked things to match the PT, but he didn't. Case in point, the Emperor in ESB. I know he's been changed to Ian McD, but the hologram itself looks...bad. I mean, the old lady/monkey eyes Emperor looked more like Palpatine than this bad makeup job. If only they'd pulled down the hood a little more and darkened the contrast, it would have been consistent with TPM and looked MUCH better.
