No they are based on faith. WTF do you think? YES, the pictures! And it's not my final judgement, just my thoughts of what I can see.
I know photos can make the figure look weird or worse than it actually is, I argued that IN SOME (note: IN SOME) of OMG's photos the figures looked deformed and the exaggerated details made it look awful. No no no, "they are perfect" people said.
The paint app looks average from what I can see. Then I don't like how you can see where the plastic parts of the chest go together on the sides and the same on the shoulders.
What I would like to see is photos of these figures in a "natural" environment, not photos taken in a photo studio where the photos have been edited as well.
I'm still getting this figure because it's Avatar dammit. James Cameron has brainwashed me, I mean: "It's the will of Eywa".
