Excuse the salacious nature of this one, but I had to share this slice of serendipity. Without using a reference image of any sort, I quick-sketched a torso that (to me) looks like I was sitting in on a 1950s Life Drawing art class. I don't think it's so much what I drew, but what your mind fills in from the lack of detail and overall softness to the shading and form. There's likely a lesson to extract from every happy art accident.
