Hi Lillendandie ...
I apologize for the late reply ... my busy season started in June with a phone call from a patron who I met back in 2013 -
with an offer that I couldn't refuse... $$
Back to your inquiry - this is not a mixed media piece.
It is a straight watercolor ... just utilizing an advanced bag of watercolor painting techniques.
PS- I've kept some of my initial attempts as a beginning watercolor painter ... I have them facing a wall in a closet.
Every once in a while I take a look at them ... just to remind myself ... of who I once was as a watercolor nubie.
It keeps me humble.
