RoboTroll Foot Rework

I'm rebuilding the RoboTroll's ankles as they would not be able to animate the way I'd like. The old setup is on the left, which side will also be surrounded by extra armor. This really only rotates around 1 axis, but my new socket joint on the right will give me full rotation around 3 axes.

I did like the look of the 3 metatarsals on the old setup, but the new setup will function the way I need it to and I still like it. The combined metatarsus has the same curvature as the split metatarsals but isn't really visible from this angle.

Old hinge joint ankle on left - new socket ankle on right.
