I love the idea of upcycling, repurposing, and making something new out of something old, don't you? That's how I like to attack an old canvas sometimes, by adding new layers over old and reinventing it a bit. These abstract landscapes happened just because I had some leftover paint and some old art that I wanted to paint over.... If you have old artwork lying around, why not try painting over it? You never know what you might discover.
Well, the canvas in the bottom right was a new one I started a month ago, but the other three were definitely upcycles. You get the idea. The bottom right canvas inspired me to paint over the other three because I was liking the layered look. The house in the top right reminds of driving through LA, with lots of buildings flying by. It's fun to be a passenger.
