Well for a first shot (or many shots later) at the blues that's a fine effort. All music connects emotionally on some level but for me blues is on a higher tier....and againthis is just my ole phart ramblings...but I think every component of a blues song needs to scream the blues.

John Lee Hooker said "every lines of a blues song has a meaning" and I'll add that every solo or fill or rhythm part needs to support the meaning. So....all this means is that I agree with gruve and floyd re the horns. They don't, IMO, support the feel that you've established. BIAB encourages a lot of experimentation and that is a great thing......so there are likely many, many folks who will think the horns work or don't distract. Heck, if you want more of a soul/RB sound than blues they sound fine. But I'd throw a gritty rhythm in there and see what happens smile

You definitely have both the vocal feel and voice timbre for this style -- many try it who don't and unfortunately never realize it.

Love the "unwelcome mat" line! Just my fav line of a great write.
