Leg Study - Digital Drawing

Here is my new digital piece of art. This time, I tried to study the human leg - the foot in particular.

The sketch depicts two human legs on the ground. One seems to be in motion and forging forward while the other foot rests on a ground as a support.

This piece was done with a blue ballpoint pen on a cardboard paper using scribble style. You can see my steps below:

Thank you.
