>Being able to rapidly prototype concepts might help people get good at it,

Again, it's hard to quantify or validate. One thing I will say is that people can often misinterpret the things that make a certain piece of art work. It's often the little details, or even the absence of detail that make or break it. This is the sort of stuff that requires you to train your eye to notice.

For example, Da Vinci is often heralded as a master of the human form and proportions (the Vitruvian man). But many of his later works often eschewed realistic proportions, with his figures often being 10-11 heads tall. This is a subtle detail that influences how a piece feels, and yet most people would completely miss it!
