Tommy,
I was finally able to download the other songs, inclusive "25 doyles".
The first thing that strikes me is that in "Somber mood" the accordeon (which seems more an harmonica, to tell the truth) is rather noisy (the sound has a dirty" quality that makes me prefer the Millenium more).
The jazzfisa sound in "25 doyles" is cleaner, but a bit "dark". I think that for this song even a musette sound would work well (the background has something of a "french" atmosphere to it).
"Man without love": again the sound has a dirty quality; definitely the Millenium is much better.
Once again, I have to say that I am really impressed by your technique!
Final comment: I think that, if you play a fast lick every now and then, it has more impact on the audience. It's the law of contrasts: you play a song slowly for 2'30", then start to improvise like hell for 30" and everybody goes "WOW"! If you improvise or play fast all the time after a while nobody notices anymore and the effect is lost.
