This is apparently my most popular photo on flickr: Lone Tree.
Apparently, this image made it to the top 25 of flickr's "explore" pages, which is not bad. This is also the one image which has received requests from various people to use - for posters, in a magazine, and for some book (which it is totally unrelated to). I've mostly told them yes, since I'm not a pro and I don't make money from my photography.
There is one thing that has always irritated me though ... the largish leaves on the right. In the foreground. They don't belong. And I can't crop them out without losing the tree.
