Only thought is that the gmk render is a bit darker looking for the alphas. Of course color samples will be given before final production, so I guess it could be adjusted lighter if need be. Which version of the renders is closer to OP's idea?
Also it looks like the groupbuy is open on Kono store, and it says it will be open until Dec 17. Is that correct, or is it going to start Dec 17? Want to get awareness of the set out there as much as possible.
