The head isn't as good as the proto in this case, but that shot you just used was even more unflattering than the one in my hand now.
If you are buying this to display with the mask up I'd say you have every right to decide to pass on it, the face isn't as good as the ones that came with the MK 2 or 3, but put simply... I don't care too much, I would have preferred a better head under there but the face plate will be permanently down on mine, and the rest of the figure is way beyond what I'd hoped for in terms of observation, engineering and articulation... right now... for me at least, it's the figure of the year. And no, I'm not a Shellhead, or at least I wasn't.
