Now that the preliminary assembly is complete, I'll proceed with the processing before seam line removal.

There's only one part of the shoulder section that needs processing, and it's quite noticeable when compared to the Exia's articulation, but I'm going to boldly cut it down.
To prevent it from coming loose easily, I've left a slight radius around the round hole of the joint to increase the strength of the fit.

Post-assembly processing of the knee joint
Here, I've cut off the protrusion that comes into contact with the joint.
