I have never actually posed myself for an artist, it is on my bucket list, but have drawn, painted, photographed and sculpted from life for decades. No manual artist actually expects their model to remain totally still for hours at a time. We always draw in twenty minute segments, and our drawings all have our own style on them. This if anyone believes DaVinci drew her exactly as she was, you need to take a drawing class.

Recently saw a documentary that pointed out pretty much EVERY woman DaVinci painted had that smile. Plus, re the model sitting for so long -- I believe Da Vinci carried that painting around for years while he worked on it.

What if it was gas?

She looks like she has hemorrhoids.
