It's unfortunate that the head had to be so small, to fit through the hole in the body section. That scale issue kinda spoils the overall look of the robot mode because your eyes are automatically drawn to a 'persons' head.
I like the colours though, and would have been nice to have the concept head shown at BotCon, which better resembled the Gen1 pretender shell head (but obviously wouldn't have worked due to the size restriction - with the horns, it would have been even smaller than the one they ended up with).
