Well, TO ME it is. It just looks weird. And being sqeezed inside the mask makes him look even more fat. Also, his mouth, cheeks...those features are all very "baby-like". You have a very mean looking suit and mask and you have a face that doesn't quite match the rest. In another shot, he looks like he has no neck. I don't know, man, his figure as Batman is just weird. He doesn't look bad in all shots, but those he does, man...they're really bad.
I think the suit is, overall, really good. But it just seems that it has the wrong guy inside. The suit shouldn't be that bulky in the first place. I know it is bulky in reference to the graphic novel, but he doesn't look comfortable at all in that suit. And taking into account what he phisically needs to do, he doesn't look like someone who could do it. Not in that suit. That's not the ideal body type for someone who moves like Batman.
