After spending a couple of days putting colour onto them, the two magnolias at the bottom left weren't sitting right with me. I didn't feel they were adding anything to the composition, so I took them out. It meant cleaning the paint back carefully with turpentine and sanding out any brush strokes with a fine grit sandpaper, so as not to leave traces of them in the surface; then painting the sky over the area that they were in. It's rare that I'll make such a major change this far into the painting, but I think it was worth the hassle. There's another couple of colour glazes to go yet and there should be no trace that they were ever there by the time I've finished.
