Her site’s About page says:

I paint in watercolor because it scares me.  I love its quirky unpredictability.  I love the twinge of anxiety I feel every time I put down a color, knowing that I’ve often only got one shot to get it right.
  I take a medium known for its softness and  unpredictability and push it to its outermost limits of saturation and control. My still life paintings are a celebration of the intricacies of the familiar and the beauty generated by the patina of time.

Still, she’s amazing! :)
