Definitely a much improved head sculpt over the BvS one we are getting guys...mine still arrives in a month. I went back over the uploaded pictures on here of the BvS version and I honestly have to say the new JL sculpt is better. The BvS face looks like an expressionless, lifeless doll next to the JL version which conveys a portrait of intensity, determination and focus. A sense of seriousness and preparedness for battle comes across viewing her face.
Yes, I agree it does look similar to the training armor version in expression but there are subtle differences around eyes and the lips. Maybe it's the same sculpt with different paint...not sure.
One thing is for sure, this JL version of Diana would beat the crap out of the the bimbo looking BvS version in a staredown contest any day of the week. And, for that reason, she is the more definitive version of Wonder Woman. Add the fur cape/cloak, and she just kicks the BvS version's butt easily because of an all around better resemblance to her appearance in the movie where she is in the WWI group photo.
Seriously, bros, which do you want? The bimbo or the badass beatch.
