I've never been to Yosemite. I'm not sure it's on my 20 things to see/do before I die list. Maybe I'll add it. I came across a beautiful painting of trees by a lake in Yosemite park while doing a search through Google images for autumn trees. It was so gorgeous I felt compelled to copy it! Next autumn, I'll go in search of my own trees by lakes in Ireland, I promise! (But we really don't get the same colours as they do in America - I saw the fall colours in Boston and Maine once, many years ago - the light was so intense and the leaves so bright, it was dazzling)
Here is my - pale - copy (Do click on the link for the original):
I've now also painted a bigger version. Will post it in the next few days!
