Blender Humanoid Armature Guidance

I’m in the middle of building a humanoid rig in Blender and I’m stuck on getting the upper-body armature right—head, neck, spine and shoulder chain down to the wrists. What I’m after is a clear, practical explanation rather than scattered tutorials. A screen-share session (or two) where you walk me through creating and naming the bones, setting correct roll, parenting, basic constraints and quick deformation tests would be perfect. I’ll supply the current .blend so you can point out what’s wrong and show the proper workflow live; a concise set of notes or a commented file afterward will help me repeat the process solo. If this sounds straightforward to you and you’re comfortable explaining Blender’s rigging tools in plain language, let’s get started.
