In drawing dynamic figures the first challenge is to get the proportion of the parts of the body correct.  After that the next challenge is to make sure that your figures are balanced.  The next stages are to begin to add a dynamic energy to the figure.  After that comes the ability to give your figure a personality.  I’m still dealing mostly with the balance and energy but I’m beginning to see, on occasion, something that actually looks like a real person.

In both these images I’m trying to use ‘line weight’ or the variety in the darkness of the pencil line to suggest lighting.
