I believe this to be true. I just don't think they're as committed to go the whole distance they can, as we'd love them to. Maybe that's not a realistic expectation. They certainly are doing a lot more than Hot Toys does, and they're still cranking out the best quality figures on the market.
But I would love to hold them more to their word. The Joker is one of my favorite figures. But that outfit leaves enough to be desired, that you can't help but think they could have pushed themselves a little further. I feel similarly about some of their other work so far.
I think the reason why certain characters like Joker or Aragorn didn’t/haven’t gotten the “near perfect” treatment is because I hardly saw people share things with them early on for those figures. Nowadays, they’re getting more and more people whom are more willing to share critical feedback. And John with INART did say, that they’d only revise things if there’s a “general consensus, not just an individual here and there.” Yes, we have a fellow collector whom shared pictures with them regarding the Aragorn braces and stitching, etc, and sure enough they fixed it! But there needs to be more people asking for these things to be optimized. Perhaps, for other costuming details, they just don’t see enough or exact feedback to where they just don’t do it.
