Simple, clean, and to the point. Great job. :)

Here, I think you did a pretty good job at rhyming, other than the last two lines. I feel that rhyming did restrict your writing a little.

"Autumn changes colors all" does not make sense no matter how you read it unless you add a comma before "all".

Either "autumn changes colors" or "autumn colors all". those three words don't fit well together.

That's IMO though.

Simple enjoyment of the seasons

I like the rhymes I love the reasons

Very simple, yet very beautifully written. There's a sense of wistfulness and innocence around here, and the rhyme scheme and choice of words are fabulous. Very nice!
