First up is my take on Challenge #1, "Simplicity":
I like the open airiness of the finished piece and yes, it did please me with what I view as its simplicity.
What do you think? Did I interpret the challenge well or would you advise something different? What does simplicity mean to you in your own artwork? Do you find it a positive or negative descriptor? Do you respond or back away from it as a challenge? Do you know why you react the way you do?
Always food for thought.....
