Good stuff. I liked the chord progression.
I'm hearing separation between the vox and backer.
I think of most rock blues as having a more embedded vox that is screamed out (with verb and delay), both to get on top of the "live" band and to add feeling.
I'm uncomfortable with the Buddy Holly Ooo-ahoo touches (because I'm old enough to have been a big fan) but they might still work if the track has some reverb/delay, which would also mix it into the backer.
Good driving backer BTW, just needs to be up front more.
One man's opinion after all.
