I like willow trees.
This makes me imagine sitting under one with someone special. ^-^ It's on a hill, there are clouds blowing by in the background. A light breeze is making the leaves swing quietly in the branches. Me and her are sitting next to each other, leaning against it, watching the sunset as we talk about our favorite memories with each other.
I think if you're going to label it as a loop, you should make less of a pause at the end. There's too long a silence, and it sounds like a song, not a loop. But it would be a nice loop, so beautiful, and brings to mind an image of a moment I wouldn't like to end, so that makes a loop perfect for it. Just cut off like three seconds of silence at the end. Just my humble opinion. It's lovely either way, I just mean that if it's a loop, it should have less silence at the end, as this sounds more like a song to me.
