OK, I'll bite...
So, this isn't the stuff I really listen to, so take my comments with that in mind...
This is a very familiar sounding 12-bar blues riff...tried and true, you can't really go wrong there. Just nothing real novel, if you know what I mean...but Stevie Ray Vaughn (R.I.P.) made a career out of the same riff, over and over and over...
Drums: In a word, monotonous...need to change it up a little, ride cymbal, fills, etc. You probably know this already...I'm used to working with a drummer so my knowledge of drum machines is limited.
Guitar: I like the lead work during the verses, but it sounds a little thin. I don't know if it's just the level or if it needs some EQ to give it a little more bite. The lead break is good, but I'd like to hear a more bluesy distortion on the lead break.
Vocals: Nice vocal work, you clearly have a good voice for this kinda tune...nice laid-back style.
All in all, a good 12-bar blues rock tune.
