trouble staying inside the lines

Like I said, I'm not much of a landscape painter. The ill-fated "green painting" devolved into a "landscape" inspired by the mustard field in Half Moon Bay, but alas, that was just too literal for me. So I sanded down the canvas and am now trying to get back to the feeling of the colors, without necessarily depicting the traditional landscape composition of foreground, horizon, sky, etc.

As you can see, I abandoned any semblance of reality. Oh boy. Enough said.
