This is a 5 minute drawing made with charcoal. 

Thanks to the charcoal, the main body curves are easy to be spotted. The figure stands shows how the feet support the human body. The drawing is not detailed, but it is a little accurate.

The drawing shows a relaxed sitting person. The drawing is made for five minutes. 

You can easily see the  shoulders are under almost 90 degrees. There is a little negative space behind the left arm of the figure. 

With a little imagination, one can see the samo person standing on the street bench or sitting on a chair while weighting for the train to arrive. This is a realistic drawing of a human stand. 

Theas three figures are a quick 30 seconds sketches each. The drawing are made with pencil. They show the figure gesture and how the figure stands.  Each figure is different than the other, not only by the pose, but also with the gesture and the expression of the figure.

The drawing shows the face emotion. This is a drawing of a friend of mine, drawn for 15 minutes in a coffeshop.

The drawing represends the human support. On the drawing, you can easily see how the person is going down to take an object laying in the negative space. The stand is unique, thanks to the figure gesture, we are able to see pretty well the human stand while going down, while holding for something or trying to reach it. The main curve - the line which makes the back shows the pressure of the back while doing suck easy action.
