Thank you both!
The story behind is that I was attracted by the technical structure made from stainless steel contrasting the fall colors and the late afternoon light.
I clearly, and in this concern successfully, focused on the steel elemenent. I only took this shot,- it looked good on the cam screen.
Unfortunately the final result leaves me (and obviously you as well) with an ungratified feeling and I want to understand why.
Thomas is right considering that sufficient balancing elements are missing in the picture left area as well as a 'soul' or a center of pictural gravity.
This corresponds to Bjørn's statement that the pic catches the eye but fails to hold the interest beyond the initial moments.
The 'nothing' seems to be irritating.
I attached a newly developed color version.
