Pen and Ink stipple landscape/townscape

Hi all. I'm new to this forum and pen and ink in general....I've only been doing it for just over a year. I work with the stippling technique, and this is my latest piece.

I took the reference photo a year ago on the first warm day of spring, so everyone was out enjoying the sunshine. I've been working on this since the end of November 2013 and am very close to finishing. This of you who do stippling will know just how time consuming the technique is. I've uploaed a few images, the first one is the latest progress as of last night, the rest are just close ups of different parts of the piece.
