Three Long Drawings

I have learned what a gesture drawing is to start. I thought before that a loose drawing of the figure was a gesture drawing. So far in class I have learned that not much more than a stick figure can express, or contain more information than a representation of what our eyes see.
For example the first 30 minute drawing has some good  quailties, but you do not see the qualities that the gesture drawing contains. The next drawing is much easier to find the correct proportion by using the long axis lines. I did not know to look for these lines in a figure until it was explained in class, but as soon as it was I understood why. It may not look like like much more than a stick figure, but it is the foundation of drawing the figure. 

                                 

Drawing with the long axis lines and a basic ribcage and pelvis, shows where and at what angle the limbs are at. When adding line variation ads a good amount of depth to my drawing compared to the first long drawing.

The figure is such a

 familiar image for our eyes to see, any flaw in the drawing pops out of the drawing quite a lot. The latest drawing I did after learning about the spinal cures, I feel looks odd.

The curves of the spine are rather difficult to get correct for me right now.  The drawing with the spinal curves seems distorted to me.  I began to add the outline of the figures lower limbs. It was not done well and it creates an odd dynamic to the drawing.  The human figure is a very complicated form to draw. Learning the figure step by step through gesture drawings has shown me that even though you can show it with lines is still difficult to get right.
