I love autumn, and have written a few pieces on it as well. Love the voice in this, very positive. I think I get caught up in being too serious in my work, and wish I could take a little time to sound more upbeat, like you have here. :)

Whenever Autumns comes by , I usually don't pay attention to when the leaves fall. I just noticed the tree's naked and that's when I know Autumn came by. Now that I think about it.. may be Autumn is really handsome, it makes the majority of the leaves fall for him. Nice Haiku. I enjoyed this one.
