I started work on the arms next, the first being the shield arm. I wanted to both extend the arms, and alter the pose, so I needed to trim off the connector on the left forearm/shield, and make one that would be a socket joint for the ball on the end of the upper arm piece.
Next was the right arm--again, in this case I had to trim the Broadside's arm to accommodate it holding the railgun like a rifle rather than the intended underslung method. I also had to greenstuff parts of it to fill in various gaps, and again lengthen the arm. Again more test fitting to ensure the proper pose, and then I glued it together.
