This is a cool song, you don't come across these that often. If I were arranging this I would add a couple of instruments to the mix. Maybe something atmospheric faintly in the background, and later, an accordion? Bring the electric guitar in earlier before it does the solo, also just in the background. It needs a counter melody to the bare guitar. Weave them in and out. I would introduce the drums and bass earlier and definitely give it a back beat on the snare. I make these suggestions in light of its length. Otherwise it will get boring. And the verse/chorus could be better delineated. I leave that up to you.
