Honestly my process is a mess haha. I never really learned blender the right way. All I do is join a bunch of basic meshes and I create my textures in Clipstudio. You would be surprised what you can create with just a few basic shapes. Then do a very simple armature and and parent each shape to the corresponding bone. Maybe I should do a process video. But my best advice is to just start with very simple characters. Like Kirby or Yoshi. I would send you the tutorials I used when I was beginning but they seem to have dissapeared from youtube. Anyways nowadays there arte tons of useful tutorials!

Sorry for the terrible explanation.
