Well I'd say that was very good indeed!
It reminded me a lot of the southern rock of the mid-to-late-70s, very Allman Brothers or for that matter Doobie Brothers. There's a definite Eric Clapton influence in there as well.
I'm not a musician myself (though I have worked in radio for many years), so take my comments with a grain of salt, but although the track is outside of the genre I generally listen to I enjoyed it. I did think that there was not as much variety in the backing tracks as maybe there could be but I did love the "sound and feel" of it. I think the structure of the track does lend itself more to lyrics and vocals than a straight instrumental, though.
Good stuff, excellent job.
