Here is the cover for reference.
You guys are right about the hair. I didn't even notice it when I looked at it really quick last night. The portrait is what I focused on. The hair from the left is definitely more detailed and resemble the cover more. I would have to give the portrait to the right as the one that looks more like the cover. The colors also look more lively on the right, but they may have chose to mute it some on the left to make it more like the cover, which doesn't work IMO.
I would like to see DC keep the portrait of the right and keep the hair from the one on the left per bionicbigfoot's side by side compare.
I actually canceled my PO a couple weeks back because I started having second thoughts about the portrait resembling the cover, but after seeing the toyfair pic, I PO'ed it back. At any rate, I don't think there is any worry about this selling out anyway. If they improve upon the hair, it would be even better.
