Hi Robert,
First off very nice music and lyric. I have songs that have the same progression (different than yours of course) throughout. In a critique i had gotten with one of my songs was. Again this is my song i speak about as a reference to think about. I was told by the person doing the critique they felt my song felt redundant to them. They told me to listen to my song from their point of view saying that what they heard was (Nice) but the feeling never changes so i took their advice and changed some things. An example of this is changing the dynamics so it builds to a chorus. Intro's ,solo's & bridges etc. are things that helped me as i thought about what if anything i wanted to change.
I also learned critiques are one opinion so take what you can use at any given time and disregard the rest because you ultimately are the one who needs to be happy with your work!
