Many thanks for the positive comments including the constructive critiques. All of them are helpful and are much appreciated. So much so that I may come back to this song at a later date and have a bash at tackling one or two of the points that were highlighted. I felt good about this song while I was recording it as I'm quite fond and familiar with the genre, but as is always the case, there are always improvements to be made which don't reveal themselves immediately.
I think that I might even try writing more songs in this style in the future.
