What name best describes this style of pen-and-ink art? I have been working with pen and ink, doing pieces of this style for more than a decade. Many times, I have been asked for a name to describe what I do, and I'm continually left with stating that it is simply "my style." 

Is there a specific style of art that would aptly describe this type of highly-detailed pen-and-ink work that uses small drawings to work together to create the whole of the piece?
So, when I first looked at it my reaction was "mosaic" was the root of the style and so I did a little digging and came across the concept of "doodle mosaic" that really seems to fit. The other reason that worked for me its the there is a Zen Doodle feel as well, the sense that the sum of the parts are creating a bigger result.
