Trapped between two house, the still winterly-bare tree is more like a skeleton, branches and twigs setting irregular counterpoints against the rectangularity of the architectural elements. In two weeks times, the shapes will be much more soothing, the leaves forming green shields for the people on the balconies.
Your city tree project (and yes, I do small self-imposed projects, too) – and this photo especially – constantly reminds me of Hundertwasser’s “Fensterrecht” and “Baumpflicht”.
