Starting a New Mosaic

I recently started work on a 5' X 5' mosaic for a new park in the city of Boston.  The installation date is June 1st so it will be a busy six weeks.  I worked out the design in colored pencil, using the muted palette of the Cinca tiles I have chosen for this project.

 The working title is City Square with Reflecting Pool.  The tiles in the middle, watery portion of the mosaic will probably be shiny to contrast with the matte ceramic tiles I am using for the buildings.  Below is the first building coming together.
