more: touch room forest

First I did a watercolor sketch, when that was approved by park naturalists, I began scribbling on the wall. For complex pieces (the watershed mural: a map of a large swath of the local area) I produce a rough then project it on the wall. There was no room here to project, and it was easier to simply sketch the rough in blue paint, refine it with a smaller brush and black paint, then use sponges, large house brushes, and eventually artists' brushes to finish.
