A Leonardo Drapery Exercise

This is a graphite drawing I did trying to copy Leonardo da Vinci's example. I also kept track of my time spent on this. I don't usually but I was curious how long this one would be. I did it in 15-20 minute sessions and it took 335 minutes, or a little more than 5 1/2 hours.
