All these works seem beautiful to me. I think they give a magical touch to the street, to the neighborhood... I don't know much about styles, I just dedicate myself to feeling what a work provokes in me. I wish my city had this type of art, paintings and order and cleanliness in the street. I think the work of art is in that set.
A different look for sure, at least for some weeks. This is a nice initiative that probably many cities around the world should hold :)
