Hi Laura: Yes! you've shown it: the whole world shows the glory of God. It's a good poem. My only suggestion is that you don't use the word "beauty" or beautiful so much. Find other words. Also, the sea is used a lot to talk about God's awe. As such, it becomes a little too cliched after a while. I'd say to try to remember some other natural thing that really affected you by its beauty or creation and discuss that.
