I recently updated my self portrait figure with the new ball joints I am currently using for all my figures. The new joints have a couple of advantages:
- The figure is easier to assemble.
- All the joints are plug joints meaning there are no more seams at the side of the figure where the joints need to be encased.
- The joints are much sturdier.
I also fused the pelvis and the abs together. While this makes the figure a little bit less articulated it also makes it a lot less wobbly.
In fact it is so sturdy now I was able to make a simple stop motion test with it:



Here are comparison pics between the old and the new figure:
