I think the sculpting and posing is quite good and I don’t think they are robotic at all as mentioned above. My issue is that the heads seem small. And when one is wearing a helmet, the head should be even bigger!

I think these look pretty good. I like that they are so customizable, but that may also be a downside. Waaay back when Palladium did the Robotech KS they did models that had the same set up for arms and hands which made them super difficult to put together, especially since all of the ends are flat.
