I am very close to telling you to leave it as it is and not change it at all, but that would be stupid. Everything, no matter how delightful, can be even more spectacular.
Some things to try to see if you like them:
+You have written a scene, basically. Now try writing a person's or animal's or even plant's reaction to this scene.
+Write it out in plain-speak. For example: "It is early summer. There is still a chill" See how many different ways you can write it out. When you're done, rewrite it as a different poem. See how different you can make it coming from the same place.
+Make it into a haiku. I have written many a haiku, and I love them.
