I believe you’re saying you’re good at rigging, but you want to learn everything else, like modeling, UV unwrapping, texturing, materials, lighting, etc. If that’s the case, then yes, there’s plenty of courses here to go from zero to hero in Blender.
I suggest to start with the basics, even if you already know how to go about Blender, there is always stuff that makes you go oh, I didn’t know Blender could do that. So The Blender Basics: https://cgcookie.com/courses/blender-basics-an-introduction-to-blender-3d-4-5-lts
And then it’s CORE, starting with Fundamentals of Mesh Modeling: https://cgcookie.com/p/core
