I am trying to do a history of the Big Leaf Maple as well, but now Blogger won't upload any more image so I only have 2. This is the next to last version with a nice orange glow in the background and a lot of stumps and branches.
Here is the final version now hanging in the spare room beside the path to Ammonite Falls. I got rid of the stumps and put in some more purple and some more white contrasting highlights on the dead braches. It is actually more painterly than appears in the photo. Done!
