This is a really nice build. It does an amazing job of conveying organic muscle, rather than mechanical parts. And it’s purist, no less (I’m pretty sure, at least).
On the topic of organic muscle, I also like that he’s not purely organic-looking; there’s a few mechanical details still showing, almost as if they’re sticking out through his skin. It’s a great way of showing that he’s still made of a bunch of biomechanical beings. It would be great if the more of the smaller mechanical details were a different colour, like the silver pistons on the back of his legs, but that’s not really possible without painting parts.
The only thing I’m not really a fan of is the head. I’ve just never really liked the idea that the Golden Skinned Being would have a straight-up Skakdi head, though I do appreciate the addition of what seem to be horns.
Overall, though, this is easily one of the best Golden Skinned Being MOCs I’ve seen, if not the best.
