After such a long wait, here's the reply I got from them:
Dear Yautja,
Thank you for your email and your patience. We are sorry to hear that this piece did not meet your expectations. Please know that every piece we make is hand-made. When human hands are painting or finishing these statues there will be subtle paint or sculpt variations you can find on every statue if you look close in enough, just as you would with any hand crafted work of art.
We want you to be satisfied with the statues that you purchase from us and we do not want you to feel stuck with something that you are unhappy with. If you are not satisfied with your Predator Bust, we will be happy to offer you a full refund for this statue. If this is how you would like to proceed, I will provide you instructions to destroy the piece so that your refund may be processed.
Please let us know how you would wish to proceed with this inquiry. If you have any questions, please do not hesitate to contact us.
Best Regards.
