It seems to me as if you used an automatic noise effect on the bar fillings. If so, I'll totally advise that you stay away from that, it's better to do it by hand... with some practice you can make it look decent, and more like the way you want it. I'll make an edit sometime later since It's really late and my eyes are closing right now haha... although I warn you, what I have in mind, will stray away somewhat of the direction you're planning so far.
