Mosaic Maps

I was thinking recently about the geometric, relatively inorganic process I use to build up the design in my papercut map cards, and tried applying it back to drawing. The first drawing I did and painted in was sold almost immediately after I finished it (I didn't even have time to scan it!):

I was also working on a larger 9x12 drawing of the same type at the time:

That one's still on hold; I took a break to finish a previous work in progress in the new mosaic style, which I think came out really well:

I also made another small map in plum, like the one in green (but more dense):

I think the first green one and the five boroughs one are the most successful at the moment. Someone recently suggested that I try making a diptych of a cut-out and a mosaic map in the same form, or influenced by each other, that could be a next step.
