Well, it's actually just a small request. I'm not really sure that the concept art on the alliances announcements are really alliances (maybe tib wars?) concept art. But I really like the Nod guy in the right side:
I've already searched for a high-res version without the alliances logo but didn't really find anything useful. But I've already found the GDI Guy as high-res wallpaper background for a c&c website. So there must be some concept art pieces around. Does anyone have a source for these?
