I have to admit, my gut reaction is that I’m not sure. Admittedly, this is only a static, partial shot on a magazine cover, so of course this could all change when we get our first proper footage, but to be honest, I’ve never really understood why they felt the costume had to be all CG in the first place. It just sounds needlessly expensive to me, versus making a physical suit.
Heck, they made physical Iron Man armour for those movies and there’s probably a stronger argument for them being CGI-only.
Having said all that, the CGI should help underline that the costume is a ring construct, which could make for interesting visuals.
As for the costume in this picture, I’m really not sure. Its instantly recognisable, but I’m not sure about the energy lines which cover the suit (although again, in motion they may help play with the fact the suit is a construct itself). The mask also brings more to mind Parallax than Hal Jordan, but that’s just being a fanboy. To be honest, its hard to really tell from this one picture.
So overall, not sure, but I’ll wait until we see proper footage. That’s usually where movie costumes shine when under proper lighting and the like.
