I'm writing while listening.
The acoustic guitar sounds pure and natural, and the drums suit it. The vocals are good in the verse, but I think your friend missed some great moments to "shine", so to speak. For example, he could've hit higher notes in the chorus to make it sound more powerful.
Overall, the composition is tight and so are the lyrics. The guitars in the chorus sort of drowned the rest of the instruments in my opinion.
