Beautiful images, Deborah. You do lovely work.
As for copyright laws, folks figure if they CAN right click and save a photo they WILL right click and save a photo. Most copyright laws only have teeth if you're willing to prosecute and most of us have neither the time nor the finances to do that. It's a shame but it's a painful reality.
Love your work. Please share more and you can leave that copyright mark as large as you please
