Creature-TD Learning Path



I’m a student, learning Maya at Home.
My dream is to work on Creatures and create the rigs, muscles, fur, hair etc.

I would like to know, what learning path to follow, for someone aspiring to become a Creature-TD?

I am learning to rig. Watching some pluralsight courses for now.

What online courses/schools teach topics related to this?

Can the experienced artists here please share some advice. I would really appreciate any help with this.
