Reading "Photo Impression and the subjective image" by Freeman Patterson and André Gallant has given me the idea to experiment in the authors' direction.
Interesting comment, Maciek. At first, I felt that the zoom in movement centering close to the focus of the arch would be compelling, but I think that you are right. The graphic line of the bent tree is very strong and bears many details. Per se, it should stay the main point of attraction. Therefore, I would redo this image with an simple out of focus background rather than a zooming in one. Thank you.
