Iconography / Multi-Panel Layout

Working on these is a very meditative process for me, I usually alternate working on each icon for fifteen minutes at a time. I can get the general composition quickly, then I revisit the icon to clean up the spacial relationships of the linework. The linework must be distributed so that the icon is easy to read, even at smaller sizes. I think the best icons look good at any size.
