I'm really liking the look of these guys. They look a lot like the Nobuseri from Samurai 7. Though, the hip joints on the Knight of Poseidon look awfully thin. Also, the legs don't seem to be able to do much. The poses feel a bit uninspired, too.
Think these are a fantastic tribute to an amazing series. I'm an FSS fan from way back. Not troubled by comments about articulation; the original Knights' designs are far more Fantasy than Function, striking for their looks - alot is left up to our suspension of disbelief, physics-wise. Limited joint movement?- well, if your Build is true to the Originals, then it wouldn't, couldn't, move much either. I say FINE work, CCY. Cheers!
