Definitely have a go with other models with what you learn with the wrangler!
It's a basic rig but depending on the model it can be enough.
The RIG course is super in-depth when it comes to further expanding what a bi-pedal rig can do. I've been using what I learnt from RIG and applying and translating it onto a quadruped robot!
Hi Chirag,
It depends on what your goal is. Certainly practice this rig on a different model as that will build your skills. (The more you do something the better you get)
And this design will be more than enough if you just want to get a character moving.
The RIG course is a big step up, as it's designed to teach some more complicated setups.
It sounds like you should apply what you have learned in this course to your own project first.
