Old Shoes - Digital Drawing

Hi all, greetings...
Here is my new digital drawing.
I drew a pair of worn out old shoes placed on a ground. Each of them has a puncture at the toe sides with the right leg bigger than the other.

I really love how the squiggles on each of them worked together to build something tangible.

This piece was done with AutoDesk sketchbook application using scribble style. You can see my steps below:

Thank you.
