WOW Frank, I don't know!! This sounds pretty good in these Hi-Def headphones of mine, and I'm thinking you might just leave a good thing alone. There are always times when we think something, that we have that is a bit old, might not sound as good as it really is, and think some changes could make it better, but I don't think this is one of those times we leave well enough alone. Everything fits together very nice in this and you might just leave it be. But, if you were to do anything at all, I would only play around with some track editing presets to see if that can make it any better, like maybe some compression or limiting. I like it the way it is right now, so these are my thoughts, but the ultimate decision is yours to make. Very nice arrangement, instrumentation, vocals and mix. Nicely done.
Peace and Blessings, John
