I don't think it looks that bad, but I reserve judgment until I see him moving.
And what is purported to be the CGI-Flaming Skull of Ghost Rider:
Alls I can say there is, I really, really hope not. Hopefully this is a really early crack at it and it will be fixed and forgotten like that first shot of Wolverine swinging around the spike on the Statue of Liberty that was never seen again after the fist trailer for X-Men. Or, maybe it's just a hoax.
The problem is that the flames don't cast any light on their surroundings, magical or not, if you can see flames, they're probably generating light. Also, if they want to be realistic, you shouldn't see so much of the skull through the flames.
Whatever, I've already spent more time analyzing this picture than I meant to.
