I had a TON of notes on Arms and Hands, and fingers. I grabbed what I thought was most important for this tutorial. It was a pain in the butt to place things in some dicernable order, so I hope it doesn't confuse!
As much as I enjoyed this and think it's a good reference, the "Arms and Hands tutorial" name was a bit of a misfile. This shows how arms move and the anatomy of the arms and shares quiclk tips on making them accurate, but doesn't teach you how to actually draw hands and arms. That said, I can not deny that if you have an idea of How to get past step one, this is a map to the end product and is full of tips and tricks.
I hear what you are saying, and appreciate the criticism. After reviewing the material the portions that instruct how to draw hands, fingers, arms, etc do appear to be there. I am not sure what type of instruction was expected. Based on your description of the problem it sounds like a requirement to instruct how to draw. That would be a different tutorial. Most of my tutorials are based on the principal that the people using them already know how to draw and that these tuts aim to strengthen their knowledge with key details to achieve realism and reasonable proportion.
I can certainly look into a tutorial on basic "drawing." I have advanced and basic drawing that mostly reflects rendering techniques. The only issue I can see going forward is that people learn differently from others and have different styles of art they wish to employ (such as anime) that actually require a completely new and different mind set and technique structure.
