I think it looks good and on par with the current HT standard, but since we've been spoilt by Adam's group shot of his joker sculpt, subconsciously we expected more out of HT, just like what they did with their Nicholson joker vs Adam's.
I think as soon as more pics of the other angles are shown, most people would agree that this looks pretty good. And if not, there's always the other sculpt to sweeten deal, since we are getting 2 joker heads for the dx 2.0.
But yeah, I think there will be a 3.0 joker in the near future, as I think the best joker head sculptor is still Adam.
