Forgot to say new on left, old on right. Same for this photo.

Im quite pleased with how I did the torso too. I cut these 1mm wide slots right down the back of the torso, then heated up the part in water to bend them into their final shape. I made the gap a bit too big so I put a little shim in there.

I do all my rough gap filling with baking soda and extra thin super glue. Fills instantly so no waiting for putty to dry.
