Good!
I thought it was good, but a little fast-paced. Not the tempo, but the progression. If you had added a few more repetitions it would have fit the theme of it being a really gentle tune. The transitions could have been a bit more subtle, too. Later on it gets a little more repetitive, but it sounds too repetitive in retrospect to the beginning section... Which really goes by too quickly. The whole mood reminds me of the Spongeball level in Battle for Bikini Bottom.
