Hi Tom,
You know I think you're one of the most talented people on here and this illustrates that perfectly. Great blend of fine playing, arrangement, vocal, melody and lyrics. It's a very strong original concept and you built some lovely lyrical ideas to illustrate the theme. It maybe needs a bridge or "C" section to just lift it away from the verse/chorus pattern for a little while. One less verse with a bridge would have improved it IMHO.
Nevertheless, superb work.
