How we can structure our songs

So, here are two images of my journal.  The first image describes two ways that you can possibly set up your song about the natural object.  The second picture is my song.  Notice that I varied the chorus in stanzas 5 and 7.  Also notice that I have 8 syllables per line for stanzas 2, 4, and 6 to keep the song steady and consistent.  Let me know if you need help!
