You just fixed the hair here correct?, and why are you using art of a T-800 Arnold instead of a actual screenshot?.
I think the figure/staction figure? looks fine, hair could be tweaked and thats it but, i'm not super picky with these release since it will totally blow away anything released prior to it.
That image may be an art one, but there are publcity stills with that lighting that I believe the shot is based on. Regardless, I picked it because, for comparison, I wanted a shot close to the figure's head and they're almost the exact same angle.
And yes, I just cleaned up the hair and brought in the hairline on his right temple a bit. The real issue with this sculpt is his hair, if they clean up the sides and shorten the top, it's there.
