Making something new out of interesting details

Just now I sat in our garden and started to sketch some interesting negative spaces that I saw, behind the trees and bushes, some parts of our car between our house and the outhouse, some wrinkles on the pool cover, a door knob, a fence, and some patterns from light and shadow behind the trees. I mixed it just as I wanted without taking notice of what was what and what things where in the background, foreground, and in between. Just trying to make an interesting and somewhat mysterious landscape out of it.
