Complete detailed Life drawing

This is my complete detailed Life drawing. The drawing was made out of a photo of a friend of mine and it is showing him in an open, semi-dynamic pose - stretching his arms and back. The widely spread arms and the somewhat visible distance between the legs speaks for a very open pose. The legs are very static and are seen staing firmly on the ground(well, atleast the leg that is visible, the other one is far enough to the right to be hidden by the bed).  The arms, however, are in a position that would be hard to hold for long - this speaks for an upcomming or past movement / dynamic pose. The spine is also visibly stretched, again showing an open, dynamic pose.
Shading seems overally successfull. It suggests detail in the drapery on and over the bed. The scene setup also works well with the contrasting dark bag between the bed and the corner of the room and the contrast between the dark floor and the lighter leg.
As for the character - the shading shows proper smooth shading for the dark pants and fairly sharp shading for the body. The shading also shows the muscle twist on the bicepses and on the lower (visible) leg.
