My first impression of this was too boost contrast and convert to black and white, my second thoughts were as uploaded too make use of the rich colours of the walls. I boosted contrast slightly and increased saturation. Also cropped to remove sign on right hand side and burnt out sky.
I also feel when taking the photoraph a step backwards or zoom out would of helped as the people in foreground and sat at the table were cropped in half, I feel more of an inclusion of the street would of aided by giving more of a lead in to the picture.
Hope you like and is of help.
