It's a nice poem, something you can stop and read and just enjoy it. It's kind of short though. short and sweet?

This is a good start for your poem. I have two suggestions for you: First, let your lines overflow. In other words, you don't have to end a phrase or sentence at the end of every line, but some of them can carry over to help it flow a little better. My other suggestion is to try and find an unusual description of fall, or something specific that you've noticed-- make your poem different, make it stand out, say something in a new way. It's not as hard as it sounds. Compare a red leaf to something else, for example. You have a great grasp of rhyme and meter, though, and this is a good start! ^_^
