It’s Stephanie Gutowski! I had an eye on that photo of hers for a while.
Fun fact: Some time back I had dreamt that I had painted her and was very pleased with the result; woke up to find out I hadn’t, much to my disgruntlement. I consider this amended now, though as usually, in my dreams my work is infinitely better! :}
