i am going to be very tree-hugging and say that i like them all *best*. It's like children: you can't pic a fave, because they all have their own unique and wonderful qualities. I have to say, though, that some of them remind me of Van Gogh's "Starry Night" I guess this would be "Starry Night, by Tree". Sort of like "Leaf, by Niggle". Yet different.
