Cem,
I cannot imagine anyone else taking this particular picture. It is unlikely to be repeated as there are so many combinations of options. Yes it's fun, but this is in no way merely a good use of color. I offer my own reactions and they are not dependant on the reasons why this composition worked for you! ?
My analysis is based not on your intent, which only you know, but on the universal symbolism that it can evoke in us, as we come to experience this new work. Allow me to take this picture very seriously.
By using the blue elements as you have, disparate things are connected as we vary approaches to the concept of "blocking passage". "Passage", itself, is important as it is the basic necessity of the master metaphor of our lives, found in all languages: "Life as a journey". In some way it has the seeds of a serious and valuable follow-up to your successful series on
"Portals". A deeper meaning is allowed each of us, as we observe and return to contemplate the image and once again ask, "What world are we entering?"
If there are more related images in this series, it will be a set of works that will garner my continued attention and interest. Right now it is fascinating and I am hooked. With siblings this image will emerge stronger.
