Trying to get proportions right

Start with a 1 hour time for this sketch but got to a point were I felt lost. I could see that hands proportions are off and I think torso is a little too wide. any critique is welcome, and tips on how fix mistakes because I am at a loss. Done as part of a practice session with pose of 30 minutes in length. My current goal is: Improve at correctly capturing the overall proportions of the human form
