Am I too late in replying?
Anyway, I'm going to throw out a random hunch; it might be
CLAMP's. That would explain why the style is familiar (after all, how many manga fans
haven't seen their art?); and I know they do promotional art for Code Geass. I saw the art-book (in raw form) somewhere on the web, too - though I didn't bother looking through it since I haven't watched the anime. I've never seen this picture, but my guess should be right...I think ^^
