The cowl whilst far from the best, still looks acceptable from certain angles. For me its instantly recognisable as the Bale Batman but I understand as a collector you don't just look at your statues for a few seconds in the distance, you eyeball it, close up, for minutes, marvelling at the intricate details and if it allows some suspension of belief that your looking at almost the real thing and the joy of seeing the very character you love in front of you, then the statue has somewhat done its job. The cowl on this one might not hold up to that level of standard.
If I were a hardcore Bale Batman fan (might be the very reason I'm unable to see the flaws to the degree that many have noted), I may struggle to keep looking at the cowl as each time I look, I'd notice it's not quite right and that would be frustrating. But the asthetics of it, it's on the prettier side, kind of makes it feel not as bad as it is. If it were ugly looking, I may not be as forgiving lol. Maybe QS went a little too much on the pretty side and lost accuracy in the process?
Bale portrait is as close to perfect as you can get, absolutely stunning sculpt, no doubt the best right now. I think the body armour and paint work looks fantastic too.
