Rigging Help


I am attempting to rig up a posing dummy of my aliens, the Birrin, using Rigify. However my first attempts were a bit… wonky. !

Here are the species https://www.deviantart.com/abiogenisis/art/The-Dance-791467157

Here is my WIP rig.

My question is, since the birrin have so many joints, should I build the limbs out of TWO rigify arm presets joined together? Or should I add more bones to the initial rigs? What is best practice.
